Data Acquisition System
ADAS3022 Data Sheet
FEATURES and buffer; and a 16-bit charge redistribution analog-to-digital
converter (ADC) with successive approximation register (SAR)
architecture. The ADAS3022 can resolve eight single-ended
inputs or four fully differential inputs up to ±24.576 V when
using ±15 V supplies. In addition, the device can accept the
commonly used bipolar differential, bipolar single-ended,
pseudo bipolar, or pseudo unipolar input signals, as shown
in Table 1, thus enabling the use of almost any direct sensor
interface. Ease of use—16-bit, 1 MSPS complete data acquisition system
High impedance, 8-channel input: >500 MΩ
Differential input voltage range: ±24.576 V maximum
High input common-mode rejection: >100 dB
User-programmable input ranges
Channel sequencer with individual channel gains
On-chip 4.096 V reference and buffer
Auxiliary input—direct interface to PulSAR ADC inputs
No latency or pipeline delay (SAR architecture)
Serial 4-wire, 1.8 V to 5 V SPI-/SPORT-compatible interface
LFCSP package (6 mm × 6 mm)
−40°C to +85°C industrial temperature range The ADAS3022 simplifies design challenges by eliminating …
