The AD7890ARZ-2 is an 8-channel 12-bit data acquisition system (DAS) from Analog Devices. It integrates an input multiplexer, an on-chip track/hold amplifier, a high-speed 12-bit ADC, a 2.5V reference, and a high-speed serial interface. The part operates from a single 5V supply and accepts an analog input range of 0V to 2.5V.
The multiplexer on the AD7890ARZ-2 is independently accessible, allowing the user to insert an antialiasing filter or signal conditioning circuitry between the multiplexer and the ADC. This enables a single antialiasing filter to be used for all eight channels. The device features a fast 12-bit ADC with a 5.9 µs conversion time and a maximum power dissipation of 50mW in normal mode, with a low-power standby mode consuming only 75µW.
The AD7890ARZ-2 is housed in a 24-SOIC surface-mount package and operates over a temperature range of -40°C to +85°C. It communicates via an SPI data interface, making it suitable for a wide range of industrial and instrumentation applications.
The AD7890ARZ-2 has a 12-bit resolution.
The sampling rate is 117 kHz (117,000 samples per second).
It has 8 single-ended analog input channels.
It operates from a single 5V supply.
The operating temperature range is -40°C to +85°C.
It is available in a 24-SOIC (0.295", 7.50mm Width) surface-mount package.
The RoHS status is listed as RoHS3 compliant, but this is unverified.
