DESCRIPTION

The ADS1202 is a precision, 80dB dynamic range, deltasigma

(ΔΣ) modulator operating from a single +5V supply.

The differential inputs are ideal for direct connections to

transducers or low-level signals. With the appropriate digital

filter and modulator rate, the device can be used to achieve

16-bit Analog-to-Digital (A/D) conversion with no missing

codes. Effective resolution of 12 bits can be maintained with

a digital filter bandwidth of 10kHz at a modulator rate of

10MHz. The ADS1202 is designed for use in medium resolution

measurement applications including current measurements,

smart transmitters, industrial process control, weigh

scales, chromatography, and portable instrumentation. It is

available in a TSSOP-8 package.
