Ultra-Low-Power, 10Msps, 8-Bit ADC
General Description
The MAX19191 is an ultra-low-power, 8-bit, 10Msps
analog-to-digital converter (ADC). The device features
a fully differential wideband track-and-hold (T/H) input.
This input has a 440MHz bandwidth and accepts fully
differential or single-ended signals. The MAX19191
delivers a typical signal-to-noise and distortion (SINAD)
of 48.6dB at an input frequency of 1.875MHz and a
sampling rate of 10Msps while consuming only
15.3mW. This ADC operates from a 2.7V to 3.6V analog
power supply. A separate 1.8V to 3.6V supply powers
the digital output driver. In addition to ultra-low operat-
ing power, the MAX19191 features three power-down
modes to conserve power during idle periods. Excellent
dynamic performance, ultra-low power, and small size
make the MAX19191 ideal for applications in imaging,
instrumentation, and digital communications.
An internal 1.024V precision bandgap reference sets the
full-scale range of the ADC to ±0.512V. A flexible refer-
ence structure allows the MAX19191 to use its internal
reference or accept an externally applied reference for
applications requiring increased accuracy.
The MAX19191 features parallel, CMOS-compatible
three-state outputs. The digital output format is offset
binary. A separate digital power input accepts a voltage
from 1.8V to 3.6V for flexible interfacing to different logic
levels. The MAX19191 is available in a 5mm
×
5mm, 28-
pin thin QFN package, and is specified for the extended
industrial (-40°C to +85°C) temperature range.
For higher sampling frequency applications, refer to the
MAX1195–MAX1198 dual 8-bit ADCs. For a dual-channel,
pin-compatible version, refer to the MAX19192 data
sheet.
