HS7541A 12–Bit CMOS Multiplying DAC
s ±0.5 LSB DNL and INL s High Stability, Segmented Architecture (3 MSB’s) s Proprietary, Low TCR Thin–Film Resistor Technology s Low Sensitivity to Output Amplifier Offset s 2KV ESD Protection on All Digital Inputs s Operates With +5V to +15V Power Supplies s AD7541/7541A Replacement s Low Cost DESCRIPTION… The HS7541A is a low–cost, high stability monolithic 12–bit CMOS 4–quadrant multiplying DAC. It is constructed using a proprietary low–TCR thin–film process that requires no laser–trimming to achieve 12–bit performance. The HS7541A is a superior pin–compatible replacement for the industry standard 7541 and AD7541A. It is available in both commercial and industrial temperature ranges. It operates with +5V to +15V power supply voltages. It is available in 18– pin plastic DIP and SOIC, and 20–pin PLCC packages.

ABSOLUTE MAXIMUM RATINGS
(TA = 25°C unless otherwise noted.) These are stress ratings only and functional operation of the device at these or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

CAUTION: ESD (ElectroStatic Discharge) sensitive device. Permanent damage may occur on unconnected devices subject to high energy electrostatic fields. Unused devices must be stored in conductive foam or shunts. Personnel should be properly grounded prior to handling this device. The protective foam should be discharged to the destination socket before devices are removed.
