AD7940BRMZ Description

Short technical summary and product information.

The AD7940BRMZ is a 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It offers a throughput rate of 100 kSPS and operates from a single 2.5V to 5.5V power supply. The device features a single-ended input and a supply-based reference.

 

Key specifications include a typical signal-to-noise ratio (SNR) of 81 dB at 10 kHz input frequency. Integral nonlinearity (INL) is typically 2 LSB, and full-scale error is 8 LSB. Maximum power dissipation is 26.4 mW, with typical power consumption of 4 mW at 3V and 17 mW at 5V at 100 kSPS. Standby current is 0.5 µA maximum.

 

The device communicates via a high-speed serial interface compatible with SPI, QSPI, MICROWIRE, and DSP. It is housed in an 8-lead MSOP package (also available in 8-TSSOP). The package is surface mount with dimensions 3mm x 3mm x 0.85mm. Operating temperature range is -40°C to 85°C.

 

Suitable for battery-powered systems, medical instruments, mobile communications, instrumentation and control systems, and remote data acquisition. The low power consumption and small package make it ideal for portable applications.
