ADC081C021CIMM/NOPB

ADC081C021CIMM/NOPB is an 8‑bit analog‑to‑digital converter in a small lead‑free package with a simple SPI‑like serial interface. It uses a successive‑approximation (SAR) architecture to convert an analog input to an 8‑bit digital word that microcontrollers can read.
Key ideas:
- Resolution: 8 bits
- Interface: SPI‑like serial data output (DOUT) with a clock (CLK) and chip select (CS)
- Input: single‑ended analog input limited by a reference voltage (Vref)
- Power/package: designed for a compact board footprint; CIMM is the package code and NOPB indicates RoHS compliant (no lead)
Typical use:
- Connect Vin to your sensor signal (within 0–Vref)
- Provide Vdd and reference as specified
- Use CS/CLK to read the 8‑bit conversion result from DOUT
Applications: low‑cost data acquisition, instrumentation, embedded sensor interfaces where 8‑bit resolution suffices.
For exact voltages, timing, and pinout, consult the datasheet. If you want, I can summarize the key figures.

Direct cross-ref within Analog Devices: ADC081S021 is the closest equivalent (8-bit, ~2.1 MSPS, SPI/Microwire interface). Other vendors with similar performance include TI’s ADC0831/ADC0832 (8-bit, 1–2 MSPS, SPI-like interface). Note: exact pinout and timing may differ; use a cross-reference tool for exact replacements.

Here are the typical features of the ADC081C021CIMM/NOPB:
- 8-bit resolution
- Maximum conversion rate up to ~2.1 MSPS
- SPI-compatible serial interface (DIN, DOUT, SCLK, CS)
- On-chip track-and-hold
- External reference input (0 to Vref) for full-scale range
- Single-ended input, 0–Vref range
- Wide operating supply (roughly 2.7–5.25 V)
- Pb-free packaging (NOPB), CIMM variant
- Low-power operation with straightforward control/triggering
Notes: exact operating conditions (Vref range, temp range, power specs) are in the datasheet for the specific package/revision.

Pin count: 8 pins (8-pin package, e.g., SOIC/DIP).
Function: 8-bit analog-to-digital converter (SAR-type) with a serial SPI-like interface. It converts an analog input (VIN) to an 8-bit digital word and communicates via CS, SCLK, DIN, and DOUT; requires VDD, GND, and VREF.

- Manufacturer: Analog Devices, Inc. (ADI).
