ADC121S051 Description

Short technical summary and product information.

The ADC121S051 from Texas Instruments is a low-power, single-channel, 12-bit CMOS analog-to-digital converter. It is designed for applications requiring a variable sample rate, specified over a range of 200 kSPS to 500 kSPS. The converter utilizes a successive-approximation register architecture with an integrated track-and-hold circuit.

This ADC features a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and common DSP interfaces. It operates from a single power supply ranging from 2.7V to 5.25V. Key electrical specifications include a typical SNR of 72 dB, DNL of +0.5/-0.25 LSB, and INL of +0.45/-0.40 LSB.

Power consumption is minimal, typically 1.7 mW at a 3.6V supply and 8.7 mW at a 5.25V supply. A power-down feature can reduce consumption to as low as 2.6 µW. The device is available in compact 6-lead WSON and SOT-23 packages, suitable for space-constrained designs.

The ADC121S051 is specified for operation over the industrial temperature range of -40°C to +85°C, making it suitable for portable systems, instrumentation, and control applications.
