The AD7908/AD7918/AD7928 are 8-channel, 1 MSPS, 8-/10-/12-bit ADCs with a sequencer. They feature fast throughput rate, low power consumption, flexible power/serial clock speed management, and a high-speed serial interface. These ADCs operate from a power supply of 2.7V to 5.25V and have a wide input bandwidth.
The AD7918 is a 10‑bit successive‑approximation ADC offering up to 1 MSPS throughput with low power consumption. It operates from a single 2.7 V to 5.25 V supply and features eight single‑ended inputs with a programmable channel sequencer.
The handbook includes detailed specifications, timing data, power‑vs‑throughput curves, serial interface information, and layout recommendations. Application hints cover grounding, decoupling, and PCB design to maximize performance.
