DESCRIPTION
The TS7003 – a single-supply, single-channel, 12-bit
analog-to-digital converter (ADC) - is a 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.

Electrical and thermal stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to any absolute maximum rating conditions for extended periods may affect device reliability and
lifetime.
