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 dr aws less than 1 mA at 300ksps. Connecting directly to any SPI™/QSPI™/ MICROWIRE™ microcontrollers and other interface - compatible 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. 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, a nd small-package-footprint attributes. As a p in-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.
