The AD7891AS-1 is a high-speed, 12-bit data acquisition system (DAS) from Analog Devices / Maxim Integrated. It integrates an 8-channel input multiplexer, an on-chip track/hold amplifier, a 12-bit ADC with a 1.6 µs conversion time, a 2.5 V reference, and a high-speed interface. The device operates from a single 5 V supply and supports analog input ranges of ±5 V and ±10 V.
This DAS is designed for applications requiring simultaneous sampling of multiple analog signals, such as data acquisition systems, motor control, and instrumentation. The serial and parallel interface options provide flexibility for connecting to microcontrollers or DSPs. The device is housed in a 44-MQFP (10x10) surface mount package and operates over a temperature range of -40°C to 85°C.
The AD7891AS-1 includes overvoltage protection on each input channel and a power-down mode for low-power operation. Its high-speed performance and integrated features make it suitable for demanding industrial and communication applications.
The AD7891AS-1 has a resolution of 12 bits.
The AD7891AS-1 has 8 analog input channels.
The maximum sampling rate is 500k samples per second.
The analog input ranges are ±5 V and ±10 V.
The operating temperature range is -40°C to 85°C.
The AD7891AS-1 is available in a 44-MQFP (10x10) surface mount package.
The device operates from a single 5 V supply.
