ADS1216

SBAS171B – JUNE 2001

8-Channel, 24-Bit

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 24 BITS NO MISSING CODES

● 0.0015% INL

The ADS1216 is a precision, wide dynamic range, delta-sigma, Analog-

to-Digital (A/D) converter with 24-bit resolution operating from 2.7V to

5.25V supplies. The delta-sigma, A/D converter provides up to 24 bits of

no missing code performance and effective resolution of 22 bits.

● 22 BITS EFFECTIVE RESOLUTION

(PGA = 1), 19 BITS (PGA = 128)

The eight input channels are multiplexed. Internal buffering can be

selected to provide a very high input impedance for direct connection to

transducers or low-level voltage signals. Burn out current sources are

provided that allow for the detection of an open or shorted sensor. An 8-

bit Digital-to-Analog (D/A) converter provides an offset correction with

a range of 50% of the FSR (Full-Scale Range).

● PGA FROM 1 TO 128

● SINGLE CYCLE SETTLING MODE

● PROGRAMMABLE DATA OUTPUT RATES

UP TO 1kHz

● ON-CHIP 1.25V/2.5V REFERENCE

The PGA (Programmable Gain Amplifier) provides selectable gains

of 1 to 128 with an effective resolution of 19 bits at a gain of 128.

The A/D conversion is accomplished with a second-order delta-

sigma modulator and programmable sinc filter. The reference input

is differential and can be used for ratiometric cancellation. The on-

board current DACs (Digital-to-Analog Converters) operate inde-

pendently with the maximum current set by an external resistor.

● EXTERNAL DIFFERENTIAL REFERENCE

OF 0.1V TO 2.5V

● ON-CHIP CALIBRATION

● SPI™ COMPATIBLE

● 2.7V TO 5.25V

● < 1mW POWER CONSUMPTION

The serial interface is SPI compatible. Eight bits of digital I/O are

also provided that can be used for input or output. The ADS1216 is

designed for high-resolution measurement applications in smart

transmitters, industrial process control, weight scales, chromatogra-

phy, and portable instrumentation.
