The MAX1195 is a 3V, dual, 8-bit analog-to-digital con- verter (ADC) featuring fully differential wideband track- and-hold (T/H) inputs, driving two ADCs. The MAX1195 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 48.5dB at an input frequency of 20MHz and a sam- pling rate of 40Msps. The T/H-driven input stages incor- porate 400MHz (-3dB) input amplifiers. The converters may also be operated with single-ended inputs. In addi- tion to low operating power, the MAX1195 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 MAX1195 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 con- trol pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing with various logic families. The MAX1195 is available in a 7mm x 7mm, 48-pin TQFP package, and is specified for th
The MAX1195 is a 3 V, dual, 8‑bit analog‑to‑digital converter optimized for low power, small size, and high‑dynamic performance. It operates from a single 2.7 V to 3.6 V supply and provides fully differential wideband track‑and‑hold inputs with up to 400 MHz bandwidth. The device includes an internal 2.048 V precision bandgap reference and selectable output formats (two’s complement or offset binary) via a control pin.
Key features include 87 mW normal‑operation power consumption, sleep and shutdown modes (9 mW and 0.3 µW), -72 dB inter‑channel crosstalk, and a 48‑pin TQFP package suitable for extended industrial temperature ranges. The datasheet also lists pin‑compatible upgrades for higher‑speed or higher‑resolution versions.
