(2) Parameters with minimum or maximum specification limits are 100% production tested at 25ºC, unless otherwise noted. Over temperature limits are based on characterization and statistical analysis. (3) Specified by design and characterization; not production tested. (4) Lowpass-filter bandwidth is 92kHz for f = 20 kHz and 20 kHz for f = 1 kHz. 7.5 Electrical Characteristics at TA = 25°C, VS = 2.2 V to 5.5 V, G = 6 V/V (1), R F = 5 kΩ, CF = 2.5 pF, VCM = (VS / 2) – 0.5 V, CL = 10 pF, RL = 10 kΩ connected to (VS / 2) – 0.5 V and PD connected to (VS+) (unless otherwise noted) (2) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT OFFSET VOLTAGE VOS Input offset voltage –0.5 0.1 0.5 mV VOS Input offset voltage TA = –40°C to +125°C –0.6 0.1 0.6 mV dVOS/dT Input offset voltage drift(3) TA = –40°C to +125°C ±0.3 ±1.5 µV/°C PSRR Power-supply rejection ratio 98 120 dB PSRR Power supply rejection ratio VS = 2.2 V to 5.5 V, VCM = (VS/2) - 0.5 V, TA = -40 to 125 ℃ 98 130 dB INPUT VOLTAGE RANGE VCM Common-mode voltage range (VS–) (VS+) – 1.1 V CMRR Common-mode rejection ratio (VS–) < VCM < (VS+) – 1.1 V 94 100 dB INPUT BIAS CURRENT IB Input bias current(3) 2 20 pA IOS Input offset current(3) 2 20 NOISE Input voltage noise (peak-to-peak) f = 0.1 Hz to 10 Hz 1.6 µVPP eN Input voltage noise density f = 10 kHz, 1/f corner at 1 kHz 3.8 nV/ √Hz iN Input current noise density f = 1 kHz 47 fA/ √Hz INPUT IMPEDANCE CIN Differential 11.5 pF Common-mode 5.5 OPEN-LOOP GAIN AOL Open-loop voltage gain (V–) + 400 mV < VO < (V+) – 400 mV 120 140 dB Phase margin 65 Degrees AC Characteristics (VS = 5 V) SSBW Small-signal bandwidth VOUT = 20 mVpp 9 MHz GBW Gain-bandwidth product G = 20 50 SR Slew rate 3-V output step (10-90%), VOCM = mid-supply 24 V/µs tS Settling time To 0.1%, 3-V step, G = 40, VOCM = mid-supply 0.75 µs To 0.01%, 3-V step, G = 40, VOCM = mid-supply 1.75 Overdrive recovery time VIN+ × Gain > VS 0.2 µs THD + N Total Harmonic Distortion Plus Noise(4) VOUT = 2 VPP, f = 1 kHz , RL = 10 kΩ -103 dB VOUT = 2 VPP, f = 20 kHz , RL = 10 kΩ -91.5 VOUT = 2 VPP, f = 1 kHz , RL = 1 kΩ -96 VOUT = 2 VPP, f = 20 kHz , RL = 1 kΩ -72.8 HD2 Second-order harmonic distortion VOUT = 2 VPP f = 20 kHz -105 dBc HD3 Third-order harmonic distortion VOUT = 2 VPP f = 20 kHz -95 OUTPUT Output Voltage swing from supply rails 8 10 mV ISC Short-circuit current 55 mA ZO Open-loop output impedance f = 1 MHz 500 Ω POWER SUPPLY IQ Quiescent current per amplifier IO = 0 mA 900 1000 µA POWER DOWN (Device Enabled When Floating) |
