In addition, it is – No Missing Codes possible to operate the ADS7947 (12-bit) at – INL: 1LSB (max) 2.1MSPS, the ADS7948 (10-bit) at 2.57MSPS, and the ADS7949 (8-bit) at 3MSPS with a short data – SNR: 72dB (min) frame optimized for the number of clocks sufficient for • Low Power: conversion with no drop in performance. The devices – 7.5mW at 2MSPS Operation feature both outstanding dc precision and excellent dynamic performance, this family of pin-compatible – Auto Power-Down at Lower Speeds: devices includes a two-channel input multiplexer and – 3.8mW at 500kSPS a low-power successive approximation register (SAR) – 0.8mW at 100kSPS ADC with an inherent sample-and-hold (S/H) input stage. – 0.16mW at 20kSPS • Wide Supply Range: The ADS7947/8/9 support a wide analog supply range that allows the full-scale input range to extend – Analog: 2.7V to 5.5V to 5V. A simple SPI™, with a digital supply that can – Digital: 1.65V to AVDD operate as low as 1.65V, allows for easy interfacing • Simple Serial Interface (SPI) to a wide variety of digital controllers. Automatic power-down can be enabled when operating at • Fully Specified from –40°C to +125°C slower speeds to dramatically reduce power • Tiny Footprint: 3mm × 3mm QFN consumption. Offered in a tiny 3mm × 3mm QFN package, the APPLICATIONS ADS7947/8/9 are fully specified over the extended • Communication Systems temperature range of –40°C to +125°C and are • Optical Networking suitable for a wide variety of data acquisition • Medical Instrumentation applications where high performance, low power, and • Battery-Powered Equipment small size are key. • Data Acquisition Systems 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 SPI is a trademark of Motorola. 3 All other trademarks are the property of their respective owners.
