ADC121C027 - 12-Bit Analog-to-Digital Converter

Download the ADC121C027 datasheet PDF. This datasheet also covers the ADC121C021 variant, as both devices belong to the same 12-bit analog-to-digital converter family and are provided as variant models within a single manufacturer datasheet.

General Description

These converters are low-power, monolithic, 12-bit, analog-to-digital converters (ADCs) that operates from a +2.7 to 5.5V supply.

The converter is based upon a successive approximation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz.

Key Features

  • 1.
  • 23 I2C-Compatible 2-Wire Interface Which Supports Standard (100kHz), Fast (400kHz), and High Speed (3.4MHz) Modes.
  • Extended Power Supply Range (+2.7V to +5.5V).
  • Up to Nine Pin-Selectable Chip Addresses (VSSOP Only).
  • Out-of-Range Alert Function.
  • Automatic Power-Down Mode while Not Converting.
  • Very Small 6-Pin SOT and 8-Pin VSSOP Packages.
  • ADC121C021Q is an Automotive Grade Product that is AEC-Q100 Grade 2 Qualified.
