3 / 67 page ADS1191 ADS1192 www.ti.com SBAS566A – DECEMBER 2011 – REVISED SEPTEMBER 2012 ELECTRICAL CHARACTERISTICS Minimum and maximum specifications apply from –40°C to +85°C. Typical specifications are at +25°C. All specifications at DVDD = 1.8 V, AVDD – AVSS = 3 V (1), V REF = 2.42 V, external fCLK = 512 kHz, data rate = 500 SPS, CFILTER = 4.7 nF (2), and gain = 6, unless otherwise noted. ADS1191, ADS1192 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 = 1.5 V ±1 nA Input bias current Input = 1.5 V, TA = –40°C to +85°C ±2 nA No lead-off 1000 M Ω Current source lead-off detection (nA range), 500 M Ω DC input impedance AVSS + 0.3 V < AIN < AVDD – 0.3 V Current source lead-off detection (µA range), 100 M Ω AVSS + 0.6 V < AIN < AVDD – 0.6 V PGA PERFORMANCE Gain settings 1, 2, 3, 4, 6, 8, 12 With a 4.7-nF capacitor on PGA output BW Bandwidth (see PGA Settings and Input Range section 8.5 kHz for details) ADC PERFORMANCE Resolution 16 Bits DR Data rate 125 8000 SPS CHANNEL PERFORMANCE (DC Performance) Gain = 6(3), 10 seconds of data 24.6 μVPP Gain = 6, 256 points, 0.5 seconds of data 24.6 25 μVPP Input-referred noise Gain settings other than 6, data rate other See Noise Measurements section than 500 SPS INL Integral nonlinearity Full-scale with gain = 6, best fit ±1 LSB Input-referred offset error ±100 μV Input-referred offset error drift 2 μV/°C Offset error with calibration 15 μV Gain error Excluding voltage reference error ±0.5 % of FS Gain drift Excluding voltage reference drift 5 ppm/°C Gain match between channels 1 % of FS CHANNEL PERFORMANCE (AC performance) CMRR Common-mode rejection ratio fCM = 50 Hz, 60 Hz (4) –95 dB PSRR Power-supply rejection ratio fPS = 50 Hz, 60 Hz 90 dB Crosstalk fIN = 50 Hz, 60 Hz –120 dB SNR Signal-to-noise ratio fIN = 10 Hz input, gain = 6 92 dB THD Total harmonic distortion 10 Hz, –0.5 dBFs –100 dB (1) Performance is applicable for 5-V operation as well. Production testing for limits is performed at 3 V. (2) CFILTER is the capacitor accross the PGA outputs; see the PGA Settings and Input Range section for details. (3) 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. (4) CMRR is measured with a common-mode signal of AVSS + 0.3 V to AVDD – 0.3 V. The values indicated are the minimum of the eight channels.
