7 / 63 page 7 DAC7760, DAC8760 www.ti.com SBAS528B – JUNE 2013 – REVISED JUNE 2016 Product Folder Links: DAC7760 DAC8760 Submit Documentation Feedback Copyright © 2013–2016, Texas Instruments Incorporated Electrical Characteristics (continued) At AVDD = 10 V to 36 V, AVSS = –18 V to 0 V, AVDD + |AVSS| ≤ 36 V, GND = 0 V, REFIN = 5-V external, and DVDD = 2.7 V to 5.5 V. For VOUT: RL = 1 kΩ, CL = 200 pF; for IOUT: RL = 300 Ω. All specifications are from TA = –40°C to 125°C, unless otherwise noted. Typical specifications are at 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT (3) Specified by design and characterization; not production tested. (4) DAC8760 and DAC7760 current output range is set by writing to RANGE bits in control register at address 0x55. (5) For 0-mA to 20-mA and 0-mA to 24-mA ranges, INL is calculated beginning from code 0x0100 for DAC8760 and from code 0x0010 for DAC7760.
