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 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 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 (5 nV/√Hz) and very-high input impedance, allowing easy interfacing to geophones 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 offset scaling registers support system calibration.
The synchronization input (SYNC) can be used to synchronize the conversions of multiple ADS1283 devices.
The ADS1283 is available in a compact 24-lead, 5-mm × 4-mm VQFN package, and is fully specified from –40°C to +85°C, with a maximum operating temperature range of –50°C to +125°C.
