HS7541A 12-Bit CMOS Multiplying DAC © Copyright 2000 Sipex Corporation 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. n ±0.5 LSB DNL and INL n High Stability, Segmented Architecture (3 MSB’s) n Proprietary, Low TCR Thin–Film Resistor Technology n Low Sensitivity to Output Amplifier Offset n 2KV ESD Protection on All Digital Inputs n Operates With +5V to +15V Power Supplies n AD7541/7541A Replacement n Low Cost D 11 (MSB) [4] D 10 [5] D 9 [6] D 8 [7] D 7 [8] D 6 [9] D 5 [10] D 4 [11] D 3 [12] D 2 [13] D 1 [14] D 0 (LSB) [15] R FB [18] VDD [16]GND [3] VREF [17] 20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 10K Ω20K Ω 20K Ω IO2 [2] IO1 [1] 10K Ω HS7541A 12–Bit CMOS Multiplying DAC

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. 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. V

Do not apply voltages higher than VDD or less than GND potential on any terminal other than VREF or VRFB . 2. The digital inputs are diode-clamp protected against ESD damage. However, permanent damage may occur on unprotected units from high-energy electrostatic fields. Keep units in conductive foam at all times until ready to use. 3. Use proper anti-static handling procedures. 4. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation at or above these specifications is not implied. Exposure to the above maximum rated conditions for extended periods may affect device reliability. 5. From T MIN to TMAX . 6. Integral Non-linearity is measured as the arithmetic mean value of the magnitudes of the greatest positive deviation and the greatest negative deviation from the theoretical value of any given input combination. 7. Differential Non-linearity is the deviation of an output step from the theoretical value of 1 LSB for any two adjacent digital input codes. 8. AC performance characteristics are included for design guidance only and are subject to sample testing only. 9. R L = 100Ω , CEXT = 13pF; all data inputs 0V to VDD or VDD to 0V; from 50% digital input change to 90% of final analog output. 10. Settling to ±0.01% FSR (strobed); all data inputs 0V to VDD or VDD to 0V. 11. V REF = 0V, DAC register alternatively loaded with all 0’s and all 1’s. 12. V REF = 20VP-P; F = 10kHz sinewave. 13. V REF = 20VP-P; F = 1kHz sinewave. 14. Guaranteed by design, but not production tested. 15. Logic inputs are MOS gates. I IN typically is less than 1nA @ 25°C. 16. Accuracy is guaranteed at VDD = +15V only. 17. Measured using internal feedback resistor with DAC loaded with all 1’s. 18. All digital inputs = 0V.
