Typical specifications are at +25°C. All specifications at DVDD = 1.8V, AVDD – AVSS = 3V, VREF = 2.4V, external fCLK = 2.048MHz, data rate = 500SPS, and gain = 6, unless otherwise noted. ADS1194, ADS1196, ADS1198 PARAMETER TEST CONDITIONS MIN TYP MAX UNIT ANALOG INPUTS Full-scale differential input voltage ±VREF/GAIN V (AINP – AINN) See the Input Common-Mode Range Input common-mode range subsection of the PGA Settings and Input Range section Input capacitance 20 pF Input = 1.5V, TA = +25°C ±200 pA Input bias current Input = 1.5V TA = 0°C to +70°C ±1 nA No lead-off 1000 M Ω DC input impedance Current source lead-off detection 500 M Ω Pull-up resistor lead-off detection 10 M Ω PGA PERFORMANCE Gain settings 1, 2, 3, 4, 6, 8, 12 Bandwidth See Table 4 ADC PERFORMANCE Resolution No missing codes 16 Bits Data rate 125 8000 SPS CHANNEL PERFORMANCE DC Performance Gain = 6(1), 10 seconds of data 12.2 µVPP Gain = 6, 256 points, 0.5 seconds of Input-referred noise 12.6 µVPP data Gain settings other than 6 See Noise Measurements section Integral nonlinearity Full-scale with gain = 6, best fit ±1 LSB(2) Offset error ±500 μV Offset error drift 2 μV/°C Gain error Excluding voltage reference error ±0.2 ±0.5 % of FS Gain drift Excluding voltage reference drift 5 ppm/ °C Gain match between channels 0.3 % of FS AC Performance Common-mode rejection ratio (CMRR) fCM = 50Hz, 60Hz (3) –100 –105 dB Power-supply rejection ratio (PSRR) fPS = 50Hz, 60Hz 85 dB Crosstalk fIN = 50Hz, 60Hz –100 dB Signal-to-noise ratio (SNR) fIN = 10Hz input, gain = 6 97 dB Total harmonic distortion (THD) 10Hz, –0.5dBFs –95 dB DIGITAL FILTER –3dB bandwidth 0.262fDR Hz Digital filter settling Full setting 4 Conversions (1) Noise data measured in a 10-second interval. Test not performed in production. Input-referred noise is calculated with input shorted (without electrode resistance) over a 10-second interval. (2) Input referred LSB in volts = (2 × VREF/(Gain*2 16)). (3) CMRR is measured with a common-mode signal of AVSS + 0.3V to AVDD – 0.3V. The values indicated are the minimum of the eight channels.
