Adhere to the analog input voltage range as specified in the Absolute Maximum Ratings table. (2) The common-mode overvoltage detection level has a typical hysteresis of 90 mV. (3) This parameter is the –3-dB, second-order, roll-off frequency of the integrated differential input amplifier to consider for antialiasing filter designs. (4) Integral nonlinearity is defined as the maximum deviation from a straight line passing through the end-points of the ideal ADC transfer function expressed as number of LSBs or as a percent of the specified linear full-scale range FSR. (5) Offset error drift is calculated using the box method, as described by the following equation: . (6) Gain error drift is calculated using the box method, as described by the following equation: . 7.9 Electrical Characteristics: AMC1306x25 minimum and maximum specifications apply from TA = –40°C to +125°C, AVDD = 3.0 V to 5.5 V, DVDD = 2.7 V to 5.5 V, AINP = –250 mV to 250 mV, AINN = AGND, and sinc 3 filter with OSR = 256 (unless otherwise noted); typical specifications are at TA = 25°C, CLKIN = 20 MHz, AVDD = 5 V, and DVDD = 3.3 V PARAMETER TEST CONDITIONS MIN TYP MAX UNIT ANALOG INPUTS VClipping Differential input voltage before clipping output AINP – AINN ±320 mV FSR Specified linear differential full-scale voltage AINP – AINN –250 250 mV Absolute common-mode input voltage(1) (AINP – AINN) / 2 to AGND –2 AVDD V VCM Operating common-mode input voltage (AINP – AINN) / 2 to AGND –0.16 AVDD – 2.1 V VCMov Common-mode overvoltage detection level(2) (AINP – AINN) / 2 to AGND AVDD – 2 V CIN Single-ended input capacitance 2 pF CIND Differential input capacitance 1 pF IIB Input bias current Inputs shorted to AGND –82 –60 –48 µA RIN Single-ended input resistance AINN = AGND 19 kΩ RIND Differential input resistance 22 kΩ IIO Input offset current ±5 nA CMTI Common-mode transient immunity 50 100 kV/µs CMRR Common-mode rejection ratio AINP = AINN, fIN = 0 Hz, VCM min ≤ VIN ≤ VCM max –95 dB AINP = AINN, fIN from 0.1 Hz to 50 kHz, VCM min ≤ VIN ≤ VCM max –95 BW Input bandwidth(3) 900 kHz DC ACCURACY DNL Differential nonlinearity Resolution: 16 bits –0.99 0.99 LSB INL Integral nonlinearity(4) Resolution: 16 bits –4 ±1 4 LSB EO Offset error Initial, at 25°C –100 ±4.5 100 µV TCEO Offset error thermal drift(5) –1 1 µV/°C EG Gain error Initial, at 25°C –0.2% –0.005% 0.2% TCEG Gain error thermal drift(6) –40 ±20 40 ppm/°C PSRR Power-supply rejection ratio AINP = AINN = AGND, 3.0 V ≤ AVDD ≤ 5.5 V, at dc –103 dB AINP = AINN = AGND, 3.0 V ≤ AVDD ≤ 5.5 V, 10 kHz, 100-mV ripple –92 AC ACCURACY SNR Signal-to-noise ratio fIN = 1 kHz 82 86 dB SINAD Signal-to-noise + distortion fIN = 1 kHz 81.9 85.7 dB THD Total harmonic distortion 4.5 V ≤ AVDD ≤ 5.5 V, 5 MHz ≤ fCLKIN ≤ 21 MHz, fIN = 1 kHz –98 –86 dB 3.0 V ≤ AVDD ≤ 3.6 V, 5 MHz ≤ fCLKIN ≤ 20 MHz, fIN = 1 kHz –93 –85 SFDR Spurious-free dynamic range fIN = 1 kHz 83 100 dB |
