4 / 26 page DAC5652A SLAS535D – SEPTEMBER 2007 – REVISED AUGUST 2012 www.ti.com ABSOLUTE MAXIMUM RATINGS over TA (unless otherwise noted) (1) UNIT AVDD(2) –0.5 V to 4 V Supply voltage range DVDD(3) –0.5 V to 4 V Voltage between AGND and DGND –0.5 V to 0.5 V Voltage between AVDD and DVDD –4 V to 4 V DA[9:0] and DB[9:0](3) –0.5 V to DVDD + 0.5 V MODE, SLEEP, CLKA, CLKB, WRTA, WRTB(3) –0.5 V to DVDD + 0.5 V Supply voltage range IOUTA1, IOUTA2, IOUTB1, IOUTB2(2) –1 V to AVDD + 0.5 V EXTIO, BIASJ_A, BIASJ_B, GSET (2) –0.5 V to AVDD + 0.5 V Peak input current (any input) 20 mA Peak total input current (all inputs) –30 mA Operating free-air temperature range –40°C to 85°C Storage temperature range –65°C to 150°C (1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Measured with respect to AGND. (3) Measured with respect to DGND. ELECTRICAL CHARACTERISTICS over TA, AVDD = DVDD = 3.3 V, I(OUTFS) = 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 ±0.25 1 LSB 1 LSB = I(OUTFS)/2 10, T MIN to TMAX DNL Differential nonlinearity –0.5 ±0.16 0.5 LSB Analog Output Offset error Midscale value (internal reference) ±0.05 %FSR Offset mismatch Midscale 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) –1 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 V(EXTIO) Input voltage 0.1 1.25 V RI Input resistance 1 M Ω Small signal bandwidth 300 kHz (1) Measured differentially through 50 Ω to AGND. (2) Nominal full-scale current, I(OUTFS), equals 32x the I(BIAS) 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 DAC5652A 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. 4 Submit Documentation Feedback Copyright © 2007–2012, Texas Instruments Incorporated Product Folder Links: DAC5652A |
