The AD7896 is a fast, 12-bit ADC that operates from a single 2.7 V to 5.5 V supply and is housed in small 8-lead PDIP and 8-lead SOIC packages. The part contains an 8 µs successive approximation ADC, an on-chip track-and-hold amplifier, an on-chip clock, and a high speed serial interface. Output data from the AD7896 is provided via a high speed, serial interface port. This 2-wire serial interface has a serial clock input and a serial data output with the external serial clock accessing the serial data from the part. In addition to the traditional dc accuracy specifications, such as linearity, full-scale, and offset errors, the AD7896 is also speci- fied for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio. The part accepts an analog input range of 0 V to VDD and operates from a single 2.7 V to 5.5 V supply, consuming only 9 mW.
The AD7896 is a 12‑bit successive‑approximation ADC that operates from a single 2.7 V to 5.5 V supply. It is offered in compact 8‑lead PDIP and SOIC packages and includes an on‑chip track‑and‑hold amplifier, internal clock, and a two‑wire high‑speed serial interface.
The device provides up to 100 kHz throughput, 8 µs conversion time in high‑sampling mode, and an automatic power‑down feature that reduces typical power consumption to 9 mW, making it suitable for battery‑powered applications.
