ADS1283IRHFR Product Details

The ADS1283 is an extremely high-performance, single-chip, analog-to-digital converter(ADC) with an integrated, low-noise programmable gain amplifier (PGA) and two-channel inputmultiplexer (mux). The ADS1283 is suitable for the demanding needs of seismic monitoringequipment.

The converter uses a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator thatprovides outstanding noise and linearity performance. The modulator digital output is digitallyfiltered 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 asinternal self-test input connections. The PGA features outstanding low noise (5nV/√Hz) and very-high input impedance, allowing easy interfacing togeophones and hydrophones over a wide range of gains.

The digital filter provides selectable data rates from 250 to 4000 samples per second(SPS). The high-pass filter (HPF) features an adjustable corner frequency. On-chip gain and offsetscaling registers support system calibration.

The synchronization input (SYNC) can be used to synchronize the conversions of multipleADS1283 devices.

The ADS1283 is available in a compact 24-lead, 5-mm × 4-mm VQFN package, and is fullyspecified from –40°C to +85°C, with a maximum operating temperature range of –50°C to+125°C.
