AD7944BCPZ

AD7944BCPZ is a 14‑bit, high‑precision successive‑approximation ADC from Analog Devices. It converts analog signals to digital data using a SPI‑/serial‑interface, making it easy to connect to microcontrollers or FPGAs. Key traits typically include 14‑bit resolution, relatively high SAR throughput, low power consumption, and operation from a single supply. It supports both single‑ended and differential inputs with an external reference (and variants with internal reference options in some configurations). The BC PZ suffix identifies a specific RoHS‑compliant package and temperature grade; exact package type and electrical specs are in the datasheet. Common applications are data acquisition, instrumentation, sensor interfacing, and automotive/industrial controls that require high resolution and robust software‑driven conversion. For precise figures (sample rate, input ranges, reference requirements, power, and package), consult the AD7944BCPZ datasheet.

AD7944BCPZ features (typical):
- 12-bit resolution with 4-channel input multiplexing (SAR ADC)
- Serial interface: SPI-compatible for data transfer
- Internal reference option plus external reference input
- Track-and-hold input for stable conversions
- Single-supply operation: ~2.7V to 5.25V
- Low power consumption with power-down mode
- Pb-free (RoHS compliant) packaging; suitable for compact applications
- Temperature range: typically -40°C to +85°C
Note: exact specs may vary by variant; consult the datasheet for precise numbers.

- Pin count: 16 pins (in the BCPZ package).
- Function: 12-bit, 4‑channel ADC with a serial (SPI‑compatible) interface. Four analog inputs (AIN0–AIN3) are multiplexed to a 12‑bit result, with digital interface pins (CS, SCLK, DIN, DOUT) plus power/ground and reference pins.

Manufacturer: Analog Devices, Inc. (ADI). It is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits for various industries.
