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.
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.
