The AD7874BQ is a four-channel simultaneous sampling 12-bit data acquisition system (DAS) manufactured by Analog Devices. It integrates a high-speed 12-bit ADC, on-chip reference, on-chip clock, and four track/hold amplifiers that allow all input channels to be sampled simultaneously, preserving relative phase information. This makes the device particularly suitable for applications such as phased-array sonar and AC motor controllers where phase accuracy is critical.
Key electrical specifications include a ±10V input voltage range, 8 µs conversion time per channel, and a 2 µs track/hold acquisition time. The device is powered from dual ±5V supplies. The maximum sampling rate is 29 kHz when sampling all four channels simultaneously. The ADC uses a successive approximation register (SAR) architecture.
The AD7874BQ is packaged in a 28-lead ceramic DIP (CDIP) with a 0.600-inch (15.24 mm) lead spacing. It operates over a temperature range of -40°C to +85°C, making it suitable for industrial environments. The mounting type is through hole.
