3 Description
The ADS921x is an 18-bit, 10-MSPS/ch, dualchannel,
simultaneous-sampling, analog-to-digital
converter (ADC) with an integrated driver for the
ADC inputs. The ADC consumes only 180 mW/ch at
10 MSPS/ch and the power consumption scales with
lower sampling rates.
The ADS921x uses a serial low-voltage differential
signaling (SLVDS) data interface that enables highspeed
digital interface while minimizing digital
switching noise. The device comes in a space-saving,
6-mm × 6-mm, VQFN package.
The ADS921x is specified for the extended
temperature range of –40°C to +125°C.
