TS7003 A 300ksps, Single-supply, 12-Bit Serial-output ADC FEATURES DESCRIPTION Pin-Compatible, Single-channel Higher-Speed The TS7003 a single-supply, single-channel, 12-bit Upgrade to MAX1286 analog-to-digital converter (ADC) - is a successive- Single-Supply Operation: +2.7V to +3.6V approximation ADC that combines a high-bandwidth DNL & INL: 1LSB (max) track-and-hold (T/H), a high-speed serial digital 300ksps Sampling Rate interface, an internal +2.5V reference, and low Low Conversion-Mode Supply Current: conversion-mode power consumption. The TS7003 0.95mA 300ksps operates from a single +2.7V to+3.6V supply and Low Supply Current in Shutdown: 0.2A draws less than 1mA at 300ksps. Internal 10-MHzTrack-and-Hold Internal 0.6%, 30ppm/C +2.5V Reference Connecting directly to any SPI/QSPI/ SPI/QSPI/MICROWIRE 3-Wire Serial-Interface MICROWIRE microcontrollers and other interface- 8-Pin, 3mm x 3mm TDFN-EP Package compatible computing devices, the TS7003s 3-wire serial interface is easy to use and doesnt require separate, external logic. An external serial-interface clock controls the TS7003s conversion process and APPLICATIONS its output shift register operation. Process Control and Factory Automation Data and Low-frequency Signal Acquisition In PCB-space-conscious, low-power remote-sensor Portable Data Logging and data-acquisition applications, the TS7003 is an Pen Digitizers & Tablet Computers excellent choice for its low-power, ease-of-use, and Medical Instrumentation small-package-footprint attributes. Battery-powered Instruments As a pin-compatible and higher-speed upgrade to the MAX1286, the TS7003 is fully specified over the - 40C to +85C temperature range and is available in a low-profile, 8-pin 3x3mm TDFN package with an exposed back-side paddle.
