3 Description
The ADS8353, ADS7853, and ADS7253 belong to a
family of pin-compatible, dual, high-speed,
simultaneous-sampling, analog-to-digital converters
(ADCs) that support single-ended and pseudo-
differential analog inputs.
Each device includes two individually programmable
reference sources that can be used for system-level
gain calibration. Also, a flexible serial interface that
can operate over a wide power-supply range enables
easy communication with a large variety of host
controllers. Power consumption for a given
throughput can be optimized by using the two low-
power modes supported by the device. All devices
are fully specified over the extended industrial
temperature range (–40°C to 125°C) and are
available in pin-compatible, WQFN-16 (3-mm ×
3-mm) and TSSOP-16 packages.
