  • AD5307 2.5 V to 5.5 V, 400 µA, Quad Voltage Output 8-Bit DAC in a 16-Lead TSSOP

The AD7226 contains four 8-bit voltage-output digital-to-analog converters, with output buffer amplifiers and interface logic on a single monolithic chip. No external trims are required to achieve full specified performance for the part.

Separate on-chip latches are provided for each of the four D/A converters. Data is transferred into one of these data latches through a common 8-bit TTL/CMOS (5 V) compatible input port. Control inputs A0 and A1 determine which DAC is loaded when WR goes low. The control logic is speed-compatible with most 8-bit microprocessors.

Each D/A converter includes an output buffer amplifier capable of driving up to 5 mA of output current. The amplifiers’ offsets are laser-trimmed during manufacture, thereby eliminating any requirement for offset nulling.

Specified performance is guaranteed for input reference voltages from 2 V to 12.5 V with dual supplies. The part is also specified for single supply operation at a reference of 10 V.

The AD7226 is fabricated in an all ion-implanted high speed Linear Compatible CMOS (LC2MOS) process which has been specifically developed to allow high speed digital logic circuits and precision analog circuits to be integrated on the same chip.
