PRELIMINARY TS7003 Product Brief FEATURES A 300ksps, Single-supply, 12-Bit Serial-output ADC DESCRIPTION The TS7003 – a single-supply, single-channel, 12-bit analog-to-digital converter (ADC) - is Touchstone Semiconductor’s 1st successive-approximation ADC that combines a high-bandwidth track-and-hold (T/H), a high-speed serial digital interface, an internal +2.5V reference, and low conversion-mode power consumption. The TS7003 operates from a single +2.7V to+3.6V supply and draws less than 1mA at 300ksps. Pin-Compatible, Single-channel Higher-Speed Upgrade to MAX1286 Single-Supply Operation: +2.7V to +3.6V DNL & INL: ±1LSB (max) 300ksps Sampling Rate Low Conversion-Mode Supply Current: 0.95mA @ 300ksps Low Supply Current in Shutdown: 0.2µA Internal Track-and-Hold Internal +2.5V Reference SPI/QSPI/MICROWIRE 3-Wire Serial-Interface 8-Pin, 3mm x 3mm TDFN-EP Package Connecting directly to any SPI™/QSPI™/ MICROWIRE™ microcontrollers and other interfacecompatible computing devices, the TS7003’s 3-wire serial interface is easy to use and doesn’t require separate, external logic. An external serial-interface clock controls the TS7003’s conversion process and its output shift register operation. APPLICATIONS Process Control and Factory Automation Data and Low-frequency Signal Acquisition Portable Data Logging Pen Digitizers & Tablet Computers Medical Instrumentation Battery-powered Instruments In PCB-space-conscious, low-power remote-sensor and data-acquisition applications, the TS7003 is an excellent choice for its low-power, ease-of-use, and small-package-footprint attributes. As a pin-compatible and higher-speed to the MAX1286, the TS7003 is fully specified over the 40°C to +85°C temperature range and is available in a low-profile, 8-pin 3x3mm TDFN package with an exposed back-side paddle.
