1 / 8 page 10-9 August 1997 AD7541 12-Bit, Multiplying D/A Converter File Number 3107.1 Features • 12-Bit Linearity 0.01% • Pretrimmed Gain • Low Gain and Linearity Tempcos • Full Temperature Range Operation • Full Input Static Protection • TTL/CMOS Compatible • +5V to +15V Supply Range • 20mW Low Power Dissipation • Current Settling Time 1 µs to 0.01% of FSR • Four Quadrant Multiplication Description The AD7541 is a monolithic, low cost, high performance, 12-bit accurate, multiplying digital-to-analog converter (DAC). Intersil’ wafer level laser-trimmed thin-film resistors on CMOS circuitry provide true 12-bit linearity with TTL/CMOS compatible operation. Special tabbed-resistor geometries (improving time stability), full input protection from damage due to static discharge by diode clamps to V+ and ground, large IOUT1 and IOUT2 bus lines (improving superposition errors) are some of the fea- tures offered by Intersil AD7541. Pin compatible with AD7521, this DAC provides accurate four quadrant multiplication over the full military temperature range. Ordering Information PART NUMBER NONLINEARITY TEMP.
