www.ti.com SNAS402A – MAY 2007 – REVISED MARCH 2013 ADC121S655 12-Bit, 200 kSPS to 500 kSPS, Differential Input, Micro Power A/D Converter
Check for Samples: ADC121S655 FEATURES DESCRIPTION The ADC121S655 is a 12-bit, 200 kSPS to 500 kSPS
sampling Analog-to-Digital (A/D) converter that
features a fully differential, high impedance analog
input and an external reference. The reference
voltage can be varied from 1.0V to VA, with a
corresponding resolution between 244ВµV and VA
divided by 4096. 1 23 True Differential Inputs

Direct Sensor Interface Operating from a single 5V supply, the supply current
when operating at 500 kSPS is typically 1.8 mA. The
supply current drops down to 0.3 ВµA typically when
the ADC121S655 enters power-down mode. The …
