The AD974 is a four-channel, 16-bit, 200 kSPS data acquisition system with a serial interface. The part contains an input multiplexer, a high-speed 16-bit sampling ADC and a +2.5 V reference. All of this operates from a single +5 V power supply that has low power-down modes and external or internal reference voltage selection.
The AD974 is a four-channel, 16-bit data acquisition system featuring a high-speed sampling ADC and a +2.5V reference voltage. It operates from a single +5V power supply and supports multiple analog input ranges, including 0V to +4V, 0V to +5V, and -10V. The device is fabricated on Analog Devices' BiCMOS process and is available in 28-lead DIP, SOIC, and SSOP packages.
