Product details

8-bit SAR ADC in SOT-23-6 — 500kSPS throughput

The ADC081S051CIMF/NOPB is an 8-bit successive-approximation-register (SAR) ADC from Texas Instruments, sampling at 500k samples per second through a single-ended input.

SPI/DSP interface and SOT-23-6 footprint

Data is transferred via a SPI or DSP-compatible serial interface, which keeps the pin count to six in the SOT-23-6 package. The 1:1 S/H-to-ADC ratio means the sample-and-hold capacitor charges directly from the input during the acquisition phase — the source impedance driving the input should be low enough to settle within the acquisition time at 500kSPS.

Frequently asked questions

What is the sampling rate and resolution of ADC081S051CIMF/NOPB?

The ADC081S051CIMF/NOPB samples at 500k samples per second with 8-bit resolution. The SAR architecture delivers a conversion in one clock cycle per bit plus overhead, so the serial clock rate must be at least 8 × 500 kHz plus framing.

Does ADC081S051CIMF/NOPB replace ADC124S021CIMM/NOPB without rewiring?

No — the ADC124S021CIMM/NOPB is a 12-bit, 4-channel ADC in a 10-pin MSOP package with a 200kSPS sampling rate. The ADC081S051CIMF/NOPB is 8-bit, single-channel, 500kSPS in a 6-pin SOT-23-6. The pinout, resolution, channel count, and throughput are all different; a board spin is required.
