ADS7841

SBAS084B – JULY 2001

12-Bit, 4-Channel Serial Output Sampling

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

ꢀ SINGLE SUPPLY: 2.7V to 5V

The ADS7841 is a 4-channel, 12-bit sampling Analog-to-

Digital Converter (ADC) with a synchronous serial inter-

face. The resolution is programmable to either 8 bits or 12

bits. Typical power dissipation is 2mW at a 200kHz through-

put rate and a +5V supply. The reference voltage (V_REF) can

be varied between 100mV and V_CC, providing a correspond-

ing input voltage range of 0V to V_REF. The device includes

a shutdown mode which reduces power dissipation to under

15µW. The ADS7841 is tested down to 2.7V operation.

ꢀ 4-CHANNEL SINGLE-ENDED OR

2-CHANNEL DIFFERENTIAL INPUT

ꢀ UP TO 200kHz CONVERSION RATE

ꢀ ±1LSB MAX INL AND DNL

ꢀ NO MISSING CODES

ꢀ 72dB SINAD

ꢀ SERIAL INTERFACE

Low power, high speed, and on-board multiplexer make the

ADS7841 ideal for battery-operated systems such as per-

sonal digital assistants, portable multi-channel data loggers,

and measurement equipment. The serial interface also pro-

vides low-cost isolation for remote data acquisition. The

ADS7841 is available in a DIP-16 or a SSOP-16 package

and is specified over the –40°C to +125°C⁽¹⁾temperature

range.
