www.ti.com SNAS294B – MAY 2005 – REVISED MARCH 2013 ADC121S625 12-Bit, 50 ksps to 200 ksps, Differential Input, Micro Power Sampling A/D
Converter
Check for Samples: ADC121S625 FEATURES DESCRIPTION The ADC121S625 is a 12-bit, 50 ksps to 200 ksps
sampling Analog-to-Digital (A/D) converter that
features a fully differential, high impedance analog
input and an external reference. While best
performance is achieved with reference voltage
between 500mV and 2.5V, the reference voltage can
be varied from 100mV to 2.5V, with a corresponding
resolution between 49ВµV and 1.22mV. 1 2 True Differential Inputs
Ensured Performance from 50ksps to 200ksps
External Reference
High AC Common-Mode Rejection
SPIв„ў/QSPIв„ў/MICROWIRE/DSP Compatible
Serial Interface The output serial data is binary 2's complement, and
is compatible with several standards, such as SPIв„ў,
QSPIв„ў, MICROWIRE, and with many common DSP
serial interfaces. The differential input, low power,
automatic power down, and small size make the
ADC121S625 ideal for direct connection to
transducers in battery operated systems or remote
data acquisition applications. APPLICATIONS Automotive Navigation …
