The ADS1250 is a precision, wide dynamic range,
delta-sigma, analog-to-digital converter with 20-bit
resolution operating from a single +5V supply. The
delta-sigma architecture is used for wide dynamic
range and to guarantee 20 bits of no missing code
performance. An effective resolution of 18 bits (2.8ppm
of rms noise) is achieved for conversion rates up to
25kHz. The dynamic range of the converter is further
increased by providing a low-noise Programmable
Gain Amplifier (PGA) with gain stages of 1, 2, 4, or
8 for low level input signals.
The ADS1250 is designed for high-resolution measurement
applications in cardiac diagnostics, smart
transmitters, industrial process control, weigh scales,
chromatography and portable instrumentation. The
converter includes a flexible synchronous serial interface
and offers a three-wire control mode for low-cost
isolation.
The ADS1250 is a single-channel converter and is
offered in an SOL-16 package.
