Analog Devices AD7226 Quad 8-Bit D/A Converter Datasheet
The AD7226 is a monolithic chip containing four 8-bit DACs with on-chip latches and interface logic compatible with TTL/CMOS. It features separate data latches for each converter, controlled by inputs AO and Al, allowing microprocessor-compatible operation without user trims.
Each D/A converter includes an output buffer amplifier capable of driving up to 5 mA of current. The amplifiers' offsets are laser-trimmed during manufacture, eliminating the need for offset nulling. The device supports both dual supply (2 V to 12.5 V reference) and single supply operation.
