6 / 37 page  ADC12048 SNAS105B – APRIL 2000 – REVISED MARCH 2013 www.ti.com Power Supply Characteristics The following specifications apply to the ADC12048 for VA+ = VD+ = 5V, VREF+ = 4.096V, VREF− = 0.0V, 12-bit + sign conversion mode, fCLK = 12.0 MHz, RS = 25Ω, source impedance for VREF+ and VREF− ≤ 1Ω, fully differential input with fixed 2.048V common-mode voltage, and minimum acquisition time, unless otherwise specified. Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C Unit Symbol Parameter Conditions Typical(1) Limits(2) (Limit) PSS Power Supply Sensitivity VD+ = VA+ = 5.0V ±10% (3) Zero Error VREF+ = 4.096V ±0.1 LSB Full-Scale Error VREF− = 0V ±0.5 LSB Linearity Error ±0.1 LSB ID+ VD+ Digital Supply Current Start Command (Performing a conversion) with SYNC configured as an input and driven with a 214 kHz signal.

Bus width set to 13. fCLK = 12.0 MHz, Reset Mode 2.3 mA fCLK = 12.0 MHz, Conversion 2.3 4.0 mA (max) IST Standby Supply Current Standby Mode (ID+ + IA+) fCLK = Stopped 5 15 μA (max) fCLK = 12.0 MHz 100 120 μA (max) (1) Typicals are at TA = 25°C and represent most likely parametric norm. (2) Limits are ensured to AOQL (Average Outgoing Quality Level). (3) Power Supply Sensitivity is measured after an Auto-Zero and Auto Calibration cycle has been completed with VA+ and VD+ at the specified extremes. Analog MUX Inputs Characteristics The following specifications apply to the ADC12048 for VA+ = VD+ = 5V, VREF+ = 4.096V, VREF− = 0.0V, 12-Bit + sign conversion mode, fCLK = 12.0 MHz, RS = 25Ω, source impedance for VREF+ and VREF+ ≤ 1Ω, fully differential input with fixed 2.048V common-mode voltage, and minimum acquisition time, unless otherwise specified.
