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.
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, and small-package-footprint attributes.
As a pin-compatible and higher-speed upgrade 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.
