The MAX1190 is a 3.3V, dual 10-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving two ADCs. The MAX1190 is optimized for low power, small size, and high-dynamic performance for applications in imaging, instrumentation, and digital communications. This ADC operates from a single 3.1V to 3.6V supply, consuming only 492mW while delivering a typical signal-to-noise and distortion (SINAD) of 57dB at an input frequency of 60MHz and a sampling rate of 120Msps. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters can also be operated with single-ended inputs. In addition to low operating power, the MAX1190 features a 3mA sleep mode, as well as a 1µA power-down mode to conserve power during idle periods.

An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of this internal or an externally applied reference, if desired, for applications requiring increased accuracy or a different input voltage range.

The MAX1190 features parallel, CMOS-compatible three-state outputs. The digital output format can be set to two's complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing with various logic families. The MAX1190 is available in a 7mm x 7mm, 48-pin TQFP-EP package, and is specified for the extended industrial (-40°C to +85°C) temperature range.

Pin-compatible lower speed versions of the MAX1190 are also available. Refer to the MAX1180–MAX1184 data sheets for 105Msps/80Msps/65Msps/40Msps. In addition to these speed grades, this family includes two multiplexed output versions (MAX1185/MAX1186 for 20Msps/40Msps), for which digital data is presented time-interleaved and on a single, parallel 10-bit output port.

For lower speed, pin-compatible, 8-bit versions of the MAX1190, refer to the MAX1195–MAX1198 data sheets.

Product Detail

The MAX1181 Evaluation kit (EV Kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the nonmultiplexed MAX1180-MAX1184 and MAX1190 or multiplexed MAX1185 and MAX1186, dual 10-bit analog-to-digital converters (ADC). The MAX1180-MAX1186 and MAX1190 accept differential or single-ended analog inputs and the EV kit allows for evaluation of each ADC with both types of signals from one single-ended analog signal. The digital output produced by the ADC can easily be sampled with a user-provided high-speed logic analyzer or data-acquisition system. The EV kit operates from 3.0V analog and 2.0V digital power supplies. It includes circuitry that generates a clock signal from an AC signal provided by the user. The EV kit comes with the MAX1181 installed. Order free samples of the pin-compatible MAX1180, MAX1182, MAX1183, MAX1184, MAX1185, MAX1186, or MAX1190 to evaluate these parts.
