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.
