10/8/12-BIT HIGH SPEED 2.7 V microPOWER™ SAMPLING

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

•

High Throughput at Low Supply Voltage

(2.7 V V_CC

– ADS7829: 12-bit 125 KSPS

– ADS7826: 10-bit 200 KSPS

– ADS7827: 8-bit 250 KSPS

The ADS7826/27/29 is a family of 10/8/12-bit sampling

analog-to-digital converters (A/D) with assured specifi-

cations at 2.7-V supply voltage. It requires very little

power even when operating at the full sample rate. At

lower conversion rates, the high speed of the device

enables it to spend most of its time in the power down

mode— the power dissipation is less than 60 µW at 7.5

kHz.

)

•

Very Wide Operating Supply VoltageL:

2.7 V to 5.25 V (as Low as 2.0 V With Reduced

Performance)

The ADS7826/27/29 also features operation from 2.0 V

to 5 V, a synchronous serial interface, and a differential

input. The reference voltage can be set to any level

•

Rail-to-Rail, Pseudo Differential Input

Wide Reference Voltage: 50 mV to V_CC

within the range of 50 mV to V_CC

Micropower Auto Power-Down:

– Less Than 60 µW at 75 kHz, 2.7 V V_CC

Ultra-low power and small package size make the

ADS7826/27/29 family ideal for battery operated sys-

tems. It is also a perfect fit for remote data acquisition

modules, simultaneous multichannel systems, and iso-

lated data acquisition. The ADS7826/27/29 family is

available in a 3 x 3 8-pin PDSO (SON, same size as

QFN) package.

•

Low Power Down Current: 3 µA Max

Ultra Small Chip Scale Package:

8-pin 3 x 3 PDSO (SON, Same Size as QFN)
