ADS7841

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

interface. The resolution is programmable to either 8

or 12 bits. Typical power dissipation is 2mW at a

200kHz throughput rate and a +5V supply. The refer-

ence voltage (V_REF) can be varied between 100mV and

V_CC, providing a corresponding input voltage range of

0V to V_REF. The device includes a shutdown mode

which reduces power dissipation to under 15µW. The

ADS7841 is guaranteed down to 2.7V operation.

● 4-CHANNEL SINGLE-ENDED OR

2-CHANNEL DIFFERENTIAL INPUT

● UP TO 200kHz CONVERSION RATE

● ±1 LSB MAX INL AND DNL

● GUARANTEED NO MISSING CODES

● 72dB SINAD

● SERIAL INTERFACE

● 16-PIN PDIP OR 16-LEAD SSOP PACKAGE

● ALTERNATE SOURCE FOR MAX1247

Low power, high speed, and on-board multiplexer

make the ADS7841 ideal for battery operated systems

such as personal digital assistants, portable multi-

channel data loggers, and measurement equipment.

The serial interface also provides low-cost isolation

for remote data acquisition. The ADS7841 is available

in a 16-pin PDIP or a 16-lead SSOP package and is

guaranteed over the –40°C to +85°C temperature range.

APPLICATIONS
