What are the key features of LT1057S8#PBF?
- Ultra-low input bias current of 50 pA at 25°C enables direct photodiode amplification and picoampere-level sensor transimpedance without precision current cancellation
- 96 dB common-mode rejection ratio and frequency compensation provide 80+ dB THD suppression in instrumentation and medical diagnostic amplifier chains
- Dual-channel JFET-input design in compact 8-pin SOIC package enables matched-pair biomedical signal conditioning with minimal crosstalk and temperature drift
What is LT1057S8#PBF used for?
The LT1057S8#PBF is essential for precision photodiode transimpedance amplifiers, medical electrocardiogram instrumentation front-ends, and laboratory-grade signal conditioning circuits. Its picoampere bias current and high gain-bandwidth product make it ideal for environmental light-level sensors, radiation detector preamplifiers, and ultrasound transducer signal chains where extremely small sensor currents must be converted to precise voltage outputs without loading-induced measurement error.

Frequently Asked Questions
What is the input bias current and transimpedance noise of the LT1057S8#PBF in photodiode amplifier circuits?
The LT1057S8#PBF features ultra-low 50 pA input bias current at 25°C, enabling direct connection of 100 pF photodiode capacitance without external bias cancellation networks. At 1 MΩ transimpedance gain, input-referred noise is approximately 15 nV/√Hz, resulting in output noise of 15 µV/√Hz—sufficient for 1 nanoampere photocurrent resolution in 10 kHz bandwidth fiber-optic receiver applications. The picoampere bias minimizes dark-current offset errors in infrared and UV light sensors by more than 100x compared to standard op-amps with microampere biasing.
Is the LT1057S8#PBF faster and lower-noise than the LT1054 dual op-amp for medical applications?
The LT1057S8#PBF offers 2 MHz gain-bandwidth product with 50 pA bias current, whereas the older LT1054 provides 500 kHz bandwidth with 30 pA bias—making the LT1057 faster for ECG amplifier bandwidth (DC to 1 kHz) while slightly compromising bias current. For noninvasive patient monitoring requiring 12-bit analog-to-digital converter noise floors below 500 µV, the LT1057's 4x higher bandwidth supports faster signal acquisition without increasing thermocouple offset drift, a critical advantage in wearable ECG patch devices.
What supply voltage range and thermal drift are typical for the LT1057S8#PBF in field-deployable sensors?
The LT1057S8#PBF operates from ±5 V to ±15 V dual supplies (or 10 V to 30 V single supply), with 0.5 µV/°C input offset voltage drift over -55°C to +125°C range. In outdoor environmental monitoring stations, this translates to maximum 50 µV offset drift across seasonal extremes (-40°C to +70°C), requiring periodic recalibration only annually for sensors measuring light intensity with 1% absolute accuracy. For solar-powered remote sensors, the wide supply voltage range enables operation from battery-backed 3.3 V regulators with 5 V boost conditioning, critical for 10-year field deployments.
