SBAS541A – MAY 2011 – REVISED AUGUST 2011 www.ti.com 12-Bit, 1MSPS, 4-/8-Channel, Bipolar-Input, SAR Analog-to-Digital Converter
with Software-Selectable Ranges
Check for Samples: ADS8634, ADS8638 FEATURES DESCRIPTION The ADS8634 and ADS8638 (ADS8634/8) are 12-bit
analog-to-digital converters (ADCs) capable of
measuring inputs up to В±10V at 1MSPS. Using a
successive approximation register (SAR) core, these
ADCs provide a sample-and-hold front-end with no
latency in conversions. The ADS8634 includes an
input multiplexer (mux) for measuring up to four
inputs. The ADS8638 can measure up to eight inputs. 1 23 Selectable Input Range:
В±10V, В±5V, В±2.5V, 0V to 10V, or
0V to 5V
Up to В±12V with External Reference
No Latent Conversions Up to 1MSPS
Outstanding Performance:
12 Bits No Missing Codes
INL: В±0.9LSB
SNR: 71.8dB
Highly Integrated:
4-or 8-Channel Input Mux
Temperature Sensor …
