6 / 28 page DAC5652-EP SGLS341C – JUNE 2006 – REVISED APRIL 2013 www.ti.com ELECTRICAL CHARACTERISTICS over operating free-air temperature range, AVDD = DVDD = 3.3 V, IOUTFS = 20 mA, independent gain set mode (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT DC Specifications Resolution 10 Bits DC Accuracy(1) INL Integral nonlinearity 1 LSB = IOUTFS/2 10, T MIN to TMAX –1 ±0.25 1 LSB DNL Differential nonlinearity 1 LSB = IOUTFS/2 10, T MIN to TMAX –0.5 ±0.16 0.5 LSB Analog Output Offset error Mid-scale value (internal reference) ±0.05 %FSR Offset mismatch Mid-scale value (internal reference) ±0.03 %FSR Gain error With internal reference ±0.75 %FSR Minimum full-scale output current(2) 2 mA Maximum full-scale output current(2) 20 mA Gain mismatch With internal reference –2 0.2 2 %FSR Output voltage compliance range(3) –0.8 1.25 V RO Output resistance 300 k Ω CO Output capacitance 5 pF Reference Output Reference voltage 1.14 1.2 1.26 V Reference output current(4) 100 nA Reference Input VEXTIO Input voltage 0.1 1.25 V RI Input resistance 1 M Ω Small signal bandwidth 300 kHz CI Input capacitance 100 pF Temperature Coefficients Offset drift 2 ppm of FSR/°C With external reference ±20 Gain drift ppm of FSR/°C With internal reference ±40 Reference voltage drift ±20 ppm/°C (1) Measured differentially through 50 Ω to AGND. (2) Nominal full-scale current, IOUTFS, equals 32× the IBIAS current. (3) The lower limit of the output compliance is determined by the CMOS process. Exceeding this limit may result in transistor breakdown, resulting in reduced reliability of the DAC5652 device. The upper limit of the output compliance is determined by the load resistors and full-scale output current. Exceeding the upper limit adversely affects distortion performance and integral nonlinearity. (4) Use an external buffer amplifier with high-impedance input to drive any external load. 6 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: DAC5652-EP |
