1 / 8 page 1 ® FN3107.3 AD7541 12-Bit, Multiplying D/A Converter 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 features offered by Intersil AD7541. 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 Pinout AD7541 (PDIP) TOP VIEW Functional Block Diagram NOTE: Switches shown for digital inputs “High”. 10 11 12 13 14 15 16 17 18 9 8 7 6 5 4 3 2 1 RFEEDBACK V+ BIT 12 (LSB) BIT 11 BIT 10 BIT 9 BIT 8 VREF IN BIT 7 IOUT1 IOUT2 GND BIT 1 (MSB) BIT 2 BIT 3 BIT 5 BIT 4 BIT 6 MSB (4) 20k Ω (3) BIT 3 BIT 2 VREF IN 20k Ω 20k Ω 20k Ω 20k Ω 20k Ω 10k Ω 10k Ω 10k Ω 10k Ω SPDT NMOS 10k Ω IOUT2 (2) IOUT1 (1) RFEEDBACK (17) SWITCHES (18) (5) (6) Part Number Information PART NUMBER NONLINEARITY TEMP.
