ADC081C021CIMK/NOPB Description

Short technical summary and product information.

The ADC081C021CIMK/NOPB is an 8-bit successive approximation register (SAR) analog-to-digital converter from Texas Instruments. It features a maximum sampling rate of 188.9 ksps and a single-ended input channel. The device communicates via an I2C-compatible interface supporting standard, fast, and high-speed modes (up to 3.4 MHz).

 

Key electrical specifications include a supply voltage range of 2.7V to 5.5V for both analog and digital supplies, typical power consumption of 0.26 mW at 22 ksps (3V supply) and 0.78 mW (5V supply). The converter offers excellent linearity with maximum INL and DNL of ±0.2 LSB, and a typical SNR of 49.8 dB. Conversion time is 1 µs typical.

 

The ADC081C021 is available in a compact TSOT-23-6 surface-mount package, suitable for space-constrained designs. It includes an out-of-range alert function and automatic power-down mode to reduce power consumption when not converting. Operating temperature range is -40°C to 105°C.
