MAX1040-MAX1049 is an integrated multichannel 10-bit analog-to-digital converter (ADC) and a quad 10-bit digital-to-analog converter (DAC) in a single IC, also including a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The ADC is available in a 4 or an 8 input-channel version. The four DAC outputs settle within 2.0µs, and the ADC has a 300ksps conversion rate. All devices include an internal reference (2.5V or 4.096V) providing a well-regulated, low-noise reference for both the ADC and DAC. Programmable reference modes for the ADC and DAC allow the use of an internal reference, an external reference, or a combination of both. Features such as an internal ±1°C accurate temperature sensor, FIFO, scan modes, programmable internal or external clock modes, data averaging, and AutoShutdown™ allow users to minimize both power consumption and proces- sor requirements. The low glitch energy (4nV•s) and low digital feedthrough (0.5nV•s) of the integrated quad DACs make these devices ideal for digital control of fast-response closed-loop systems. The devices are guaranteed to operate with a supply volt- age from +2.7V to +3.6V (MAX1041/MAX1043/MAX1047/ MAX1049) and from +4.75V to +5.25V (MAX1040/ MAX1042/MAX1046/MAX1048). These devices consume 2.5mA at 300ksps throughput, only 22µA at 1ksps throughput, and under 0.2µA in the shutdown mode.

The MAX104 is a PECL-compatible, 1Gsps, 8-bit analog-to-digital converter (ADC) that allows accurate digitizing of analog signals with bandwidths up to 2.2GHz. It is fabricated on Maxim's proprietary advanced GST-2 bipolar process, integrating a high-performance track/hold (T/H) amplifier and a quantizer on a single monolithic die. The innovative design of the internal T/H, which has an exceptionally wide 2.2GHz full-power input bandwidth, results in high performance (greater than 7.5 effective bits) at the Nyquist frequency. A fully differential comparator design and decoding circuitry reduce out-of-sequence code errors (thermometer bubbles or sparkle codes) and provide excellent metastable performance of one error per 1016 clock cycles. Unlike other ADCs that can have errors resulting in false full- or zero-scale outputs, the MAX104 limits the error magnitude to 1LSB. The analog input is designed for either differential or single-ended use with a ±250mV input voltage range. Dual, differential, PECL-compatible output data paths ensure easy interfacing and include an 8:16 demultiplexer feature that reduces output data rates to one-half the sampling clock rate. The PECL outputs can be operated from any supply between +3V to +5V for compatibility with +3.3V or +5V referenced systems. Control inputs are provided for interleaving additional MAX10

The MAX1038 evaluation kit is designed to evaluate the MAX1038. The MAX1038 is an 8-bit, 12-channel (six-differential-channel) ADC with a 2-wire serial interface. The MAX1038 EV kit board supports three standard 2-wire serial interface speeds: standard mode (S-Mode), fast mode (F-Mode), and high-speed mode (HS-Mode); however, the software provided with this EV kit only supports standard mode. The provided Windows 95/98® software uses the parallel (printer) port of an IBM-compatible PC to emulate a processor with a 2-wire serial interface (S-Mode). The Windows software also provides a friendly graphical user interface (GUI) to exercise the features of the MAX1038 with control buttons and pulldown menus.

The MAX101 is an ECL-compatible ADC with a sampling rate of 500Msps and 8-bit resolution. It accurately digitizes analog signals from DC to 250MHz (Nyquist frequency). The MAX101 is designed using Maxim's proprietary advanced bipolar processes and features a high-performance T/H amplifier and two quantizers. The innovative design of the internal T/H ensures an exceptionally wide 1.2GHz input bandwidth and aperture delay uncertainty of less than 2ps, resulting in a high 7.0 effective bits at the Nyquist frequency. Special comparator output design and decoding circuitry reduce out-of-sequence code errors. The probability of erroneous codes due to metastable states is reduced to less than 1 error per 10^15 clock cycles. Unlike other ADCs that can have errors resulting in false full-scale or zero-scale outputs, the MAX101 keeps the error magnitude to less than 1LSB. The analog input is designed for either differential or single-ended use with a ±270mV range. Sense pins for the reference input allow full-scale calibration of the input range or facilitate ratiometric use. Phase adjustment is available to optimize the relative sampling of the converter halves. Input clock phasing is also available for interleaving several MAX101s for higher effective sampling rates.

The MAX100 evaluation kit (EV kit) allows high-speed digitizing of analog signals at 250Msps, using the MAX100 ADC. All circuitry required to support the ADC is supplied. Data output is available in three formats: divide-by-1, divide-by-2, or divide-by-5 mode. Clocking is provided by an external clock source input through an SMA connector. The MAX100 EV kit main board comes complete with a MAX100 high-speed, 8-bit flash ADC with strobed comparators, latched outputs, and an internal track/hold. Analog input to the board is through two SMA coaxial connectors, for use with either differential or single-ended inputs. Signals from the main board include dual-output data paths that allow easy interfacing to external circuitry. These two outputs can be configured either to provide two identical fast outputs (A and B), or an 8-to-16 demultiplexer mode that reduces the output data rates to one-half the sample clock rate. This demux is internal to the MAX100 ADC and is one of the key features of this device. A termination board with 50Ω ECL pull-down resistors is also supplied, and is connected to the main board with a 3x32 pin EURO-card connector. It provides access to the converter output data and provides proper ECL data termination. In addition to the pull-down resistors, this board has two ranks of square pins, each providing eight differential data outputs plus clock outputs. Either AData or BData may be observed with a high-speed logic
