Description of product

ADS1283 Ultra-High-Resolution Delta-Sigma ADC

Texas Instruments ADS1283 Ultra-High-Resolution Delta-Sigma Analog-to-Digital Converter (ADC) is an extremely high-performance, single-chip, analog-to-digital converter (ADC). The device includes an integrated low-noise programmable gain amplifier (PGA) and a two-channel input multiplexer (mux). The ADS1283 is suitable for the demanding needs of seismic monitoring equipment. The converter uses a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator that provides outstanding noise and linearity performance. The modulator's digital output is digitally filtered and decimated by the on-chip digital filter to yield the ADC conversion result. The flexible input mux provides an additional external input for measurement, as well as internal self-test input connections. The PGA features outstanding low noise (5nV/√Hz) and very-high input impedance, allowing easy interfacing to geophones and hydrophones over a wide range of gains.
