The MAX1196 is a 3V, dual 8-bit analog-to-digital converter (ADC) featuring fully differential wideband track-and-hold (T/H) inputs, driving two ADCs. The MAX1196 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 2.7V to 3.6V supply, consuming only 87mW while delivering a typical signal-to-noise and distortion (SINAD) of 48.4dB at an input frequency of 20MHz and a sampling rate of 40Msps. 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 MAX1196 features a 3mA sleep mode as well as a 0.1µA 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 MAX1196 features parallel, multiplexed, 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. The MAX1196 is available in a 7mm x 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) temperature range.

See a parametric table of the complete family of pin-compatible, 8-bit high-speed ADCs.

For a 10-bit, pin-compatible upgrade, refer to the MAX1186 data sheet. With the N.C. pins of the MAX1196 internally pulled down to ground, this ADC becomes a drop-in replacement for the MAX1186.

  • Product Detail

    The MAX1198 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX1195-MAX1198 dual 8-bit analog-to-digital converters (ADCs). The MAX1195-MAX1198 accept differential or single-ended analog inputs and the EV kit allows for evaluation of each ADC with both types of inputs from one single-ended analog signal. The digital output produced by the ADC can be easily sampled with a user-provided high-speed logic analyzer or data-acquisition system. The EV kit operates from 3.3V and 2.5V (MAX1198) power supplies. It includes circuitry that generates a clock signal from an AC signal provided by the user. The EV kit comes with the MAX1198 installed. Order free samples of the pin-compatible MAX1195, MAX1196, or MAX1197 to evaluate these parts.
