2 / 18 page 1.5Msps, Single-Supply, Low-Power, True- Differential, 12-Bit ADCs with Internal Reference 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (VDD = +2.7V to +3.6V, VL = VDD, fSCLK = 24MHz, 50% duty cycle, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. VDD to GND ..............................................................-0.3V to +6V VL to GND ................-0.3V to the lower of (VDD + 0.3V) and +6V Digital Inputs to GND .................-0.3V to the lower of (VDD + 0.3V) and +6V Digital Output to GND ....................-0.3V to the lower of (VL + 0.3V) and +6V Analog Inputs and REF to GND..........-0.3V to the lower of (VDD + 0.3V) and +6V RGND to GND .......................................................-0.3V to +0.3V Maximum Current into Any Pin............................................50mA Continuous Power Dissipation (TA = +70°C) 12-Pin TQFN (derate 16.9mW/°C above +70°C) ......1349mW Operating Temperature Range MAX127_ _ ETC ..............................................-40°C to +85°C Junction Temperature ......................................................+150°C Storage Temperature Range .............................-60°C to +150°C Lead Temperature (soldering, 10s) .................................+300°C PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS DC ACCURACY Resolution 12 Bits MAX127_A -1.0 +1.0 Relative Accuracy (Note 1) INL MAX127_B -1.5 +1.5 LSB MAX127_A -1.0 +1.0 Differential Nonlinearity (Note 2) DNL MAX127_B -1.0 +1.5 LSB Offset Error ±8.0 LSB Offset-Error Temperature Coefficient ±1 ppm/°C Gain Error Offset nulled ±6.0 LSB Gain Temperature Coefficient ±2 ppm/°C DYNAMIC SPECIFICATIONS (fIN = 525kHz sine wave, VIN = VREF, unless otherwise noted.)
