Input bias currents and capacitive load driving capabilities are superior to the similar LT1884 and LT1885 amplifiers, at the cost of a slight loss in speed. Input offset voltage is trimmed to less than 50μV and the low drift maintains this accuracy over the operating temperature range. Input bias currents are an ultralow 200pA maximum. The amplifiers work on any total power supply voltage between 2.7V and 36V (fully specified from 5V to ±15V). Output voltage swings to within 40mV of the negative supply and 220mV of the positive supply make these amplifiers good choices for low voltage single supply operation. Capacitive loads up to 1000pF can be driven directly in unity-gain follower applications.

The dual LT1881 and LT1881A are available with standard pinouts in S8 and PDIP packages. The quad LT1882 is in a 14-pin SO package.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The inputs are protected by internal resistors and back-to-back diodes. If the differential input voltage exceeds ±0.7V, the input current should be limited externally to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum. Note 4: The LT1881C/LT1882C and LT1881I/LT1882I are guaranteed functional over the operating temperature range of – 40°C to 85°C. The LT1882H is guaranteed functional over the operating temperature range –40°C to 125°C. The LT1882MP is guaranteed functional over the operating temperature range –55°C to 125°C. Note 5: The LT1881C/LT1882C are guaranteed to meet specified performance from 0°C to 70°C. The LT1881C/LT1882C are designed, characterized and expected to meet specified performance from – 40°C to 85°C but are not tested or QA sampled at these temperatures. The LT1881I/LT1882I are guaranteed to meet specified performance from – 40°C to 85°C. The LT1882H is guaranteed to meet specified performance from –40°C to 125°C. The LT1882MP is guaranteed to meet specified performance from –55°C to 125°C. Note 6: This parameter is not 100% tested. Note 7: Matching parameters are the difference between amplifiers A and B in the LT1881; and between amplifiers A and D and B and C in the LT1882. Note 8: This parameter is the difference between the two noninverting input bias currents. Note 9: ΔCMRR and ΔPSRR are defined as follows: CMRR and PSRR are measured in μV/V on each amplifier. The difference is calculated in μV/V and then converted to dB. Note 10: Full power bandwidth is calculated from the slew rate: FPBW = SR/2πVP. 18812fb 7 LT1881/LT1882 TYPICAL PERFORMANCE CHARACTERISTICS Supply Current per Amplifier vs Supply Voltage Slew Rate vs Supply Voltage AV = –1 AV = –1 RISING 25°C 600 –55°C 400 SLEW RATE (V/μs) 800 VS = ±15V RISING 0.4 0.35 SLEW RATE (V/μs) SUPPLY CURRENT PER AMPLIFIER (μA) 0.5 0.40 125°C 1000 0.30 0.25 FALLING 0.20 0.15 0.10 VS = ±5V 0.3 VS = ±15V FALLING VS = ±5V 0.2 0.1 200 0.05 0 0 4 8 12 16 20 24 28 TOTAL SUPPLY VOLTAGE (V) 32 0 36 0 4 8 12 16 20 24 28 32 TOTAL SUPPLY VOLTAGE (V) Settling Time vs Output Step 900 VS = ±15V AV = 1 8 6 0.1% 0.01% OUTPUT STEP (V) 4 2 0 –2 –4 0.1% 0.01% 4 0.01% 2 0 –2 0.1% 0.01% –4 –6 –6 –8 –8 –10 0 5 10 15 20 25 30 35 40 45 50 55 60 65 SETTLING TIME (μs) 0.1% GAIN BANDWIDTH PRODUCT (kHz) 6 25 50 75 100 125 150 TEMPERATURE (°C) Gain Bandwidth Product vs Supply Voltage 10 VS = ±15V AV = –1 8 0 18812 G03 Settling Time vs Output Step 10 –10 0 –50 –25 36 18812 G02 18812 G01 OUTPUT STEP (V) Slew Rate vs Temperature 0.45 1200 125°C 800 25°C 750 –55°C 700 650 600 0 5 10 15 20 25 30 35 40 45 50 55 60 65 SETTLING TIME (μs) 18812 G04 850 0 4 8 12 16 20 24 28 32 TOTAL SUPPLY VOLTAGE (V) 18812 G06 18812 G05 Phase Margin vs Supply Voltage Gain vs Frequency, AV = –1 60 36 Gain vs Frequency, AV = 1 10 10 0 0 –10 –10 –55°C 125°C 54 125°C 52 GAIN (dB) 56 GAIN (dB) PHASE MARGIN (DEG) 58 –20 VS = ±2.5V 50 VS = ±2.5V VS = ±15V –20 VS = ±15V –30 –30 48 46 0 4 8 12 16 20 24 28 32 TOTAL SUPPLY VOLTAGE (V) 36 18812 G07 –40 1k 10k 100k 1M FREQUENCY (Hz) 10M 100M 18812 G08 –40 1k 10k 100k 1M FREQUENCY (Hz) 10M 100M 18812 G09 18812fb 8 LT1881/LT1882 TYPICAL PERFORMANCE CHARACTERISTICS Gain vs Frequency with CLOAD, AV = –1 Gain vs Frequency with CLOAD, AV = 1 10 10 VS = ±15V VS = ±15V 0 0 1500pF 1800pF –10 GAIN (dB) GAIN (dB) 1000pF 500pF –20 –10 1000pF –20 500pF 0pF –30 –40 –30 1k 10k 100k 1M FREQUENCY (Hz) 10M 100M –40 0pF 1k 10k 100k 1M FREQUENCY (Hz) 18812 G10 TIME (50μs/DIV) 18812 G12 18812 G13 TIME (2μs/DIV) Small Signal Response, AV = 1, RL = 2k 18812 G15 18812 G14 Small Signal Response, AV = 1, CL = 500pF VOUT (20mV/DIV) VOUT (20mV/DIV) VOUT (20mV/DIV) Small Signal Response, AV = –1, CL = 1000pF TIME (2μs/DIV) Small Signal Response, AV = –1, No Load Large Signal Response, AV = 1 VOUT (20mV/DIV) VOUT (5V/DIV) TIME (50μs/DIV) 100M 18812 G11 VOUT (5V/DIV) Large Signal Response, AV = –1 10M TIME (2μs/DIV) 18812 G16 TIME (2μs/DIV) 18812 G17 18812fb 9 LT1881/LT1882 TYPICAL PERFORMANCE CHARACTERISTICS VOS Distribution, TA = 25°C Voltage Offset vs Temperature 200 VS = ±15V VS = ±15V 0 OFFSET VOLTAGE DRIFT (μV) 40 N8 (1 LOT) 144 S8 (2 LOTS) 184 TOTAL PARTS 100 50 0 –50 –100 –60 0 20 40 –40 –20 OUTPUT OFFSET VOLTAGE (μV) –200 –55 –35 –15 60 1400 200 0 200 400 V+ – 0 VS = ±15V 1000 800 600 400 –IBIAS 200 +IBIAS 600 0 800 10 15 –200 –55 –35 –15 20 VCM (V) V – + 0.8 V – + 0.6 V – + 0.4 VS = ±5V $VOS
