ADS1217

SBAS260 – MAY 2002

8-Channel, 24-Bit

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 24 BITS NO MISSING CODES

● INL: 0.0012% of FSR max

● FULL-SCALE INPUT = ±2V_REF

● PGA FROM 1 TO 128

The ADS1217 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

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. Burnout current sources

are provided that allow for the detection of an open or shorted sensor.

An 8-bit Digital-to-Analog Converter (DAC) provides an offset correc-

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

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

● SINGLE CYCLE SETTLING MODE

● PROGRAMMABLE DATA OUTPUT RATES

UP TO 1kHz

● ON-CHIP 1.25V/2.5V REFERENCE

● ON-CHIP CALIBRATION

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 2nd-order

delta-sigma modulator and programmable sinc filter. The refer-

ence input is differential and can be used for ratiometric cancel-

lation. The onboard current DACs operate independently with

the maximum current set by an external resistor.

● SPI™ COMPATIBLE

● POWER SUPPLY: 2.7V to 5.25V

● < 1mW POWER CONSUMPTION, V_DD= 3V

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

also provided that can be used for input or output. The ADS1217

is designed for high-resolution measurement applications in

smart transmitters, industrial process control, weigh scales,

chromatography, and portable instrumentation.

APPLICATIONS

● INDUSTRIAL PROCESS CONTROL

● LIQUID/GAS CHROMATOGRAPHY

● BLOOD ANALYSIS
