5 / 32 page ADM1069 Rev. C | Page 5 of 32 Parameter Min Typ Max Unit Test Conditions/Comments ANALOG-TO-DIGITAL CONVERTER Signal Range 0 VREFIN V The ADC can convert signals presented to the VH, VPx, and VXx pins; VPx and VH input signals are attenuated depending on the selected range; a signal at the pin corresponding to the selected range is from 0.573 V to 1.375 V at the ADC input Input Reference Voltage on REFIN Pin, VREFIN 2.048 V Resolution 12 Bits INL ±2.5 LSB Endpoint corrected, VREFIN = 2.048 V Gain Error ±0.05 % VREFIN = 2.048 V Conversion Time 0.44 ms One conversion on one channel 84 ms All eight channels selected, averaging enabled Offset Error ±2 LSB VREFIN = 2.048 V Input Noise 0.25 LSBrms Direct input (no attenuator) BUFFERED VOLTAGE OUTPUT DACs Resolution 8 Bits Code 0x80 Output Voltage Four DACs are individually selectable for centering on one of four output voltage ranges Range 1 0.592 0.6 0.603 V Range 2 0.796 0.8 0.803 V Range 3 0.996 1 1.003 V Range 4 1.246 1.25 1.253 V Output Voltage Range 601.25 mV Same range, independent of center point LSB Step Size 2.36 mV INL ±0.75 LSB Endpoint corrected DNL ±0.4 LSB Gain Error 1 % Maximum Load Current (Source) 100 μA Maximum Load Current (Sink) 100 μA Maximum Load Capacitance 50 pF Settling Time into 50 pF Load 2 μs Load Regulation 2.5 mV Per mA PSRR 60 dB DC 40 dB 100 mV step in 20 ns with 50 pF load REFERENCE OUTPUT Reference Output Voltage 2.043 2.048 2.053 V No load Load Regulation −0.25 mV Sourcing current, IDACxMAX = −100 μA +0.25 mV Sinking current, IDACxMAX = +100 μA Minimum Load Capacitance 1 μF Capacitor required for decoupling, stability PSRR 60 dB DC PROGRAMMABLE DRIVER OUTPUTS High Voltage (Charge Pump) Mode (PDO1 to PDO6) Output Impedance 500 kΩ VOH 11 12.5 14 V IOH = 0 μA 10.5 12 13.5 V IOH = 1 μA IOUTAVG 20 μA 2 V < VOH < 7 V |
