Overview
The LT1375CN8#PBF is a high-speed, low-noise dual operational amplifier manufactured by Analog Devices Inc. It features a voltage noise density of 2.9 nV/√Hz and a current noise density of 0.6 fA/√Hz at 1 kHz. The device offers a gain-bandwidth product of 14 MHz and a slew rate of 14 V/μs. It operates from supply voltages ranging from ±2.25 V to ±18 V (or 4.5 V to 36 V single supply). Input offset voltage is typically 1 mV, with a maximum of 3 mV. The component is housed in an 8-lead plastic DIP package.
Feature Summary
- Ultra-low noise performance suitable for precision signal conditioning
- High slew rate and bandwidth for fast transient response
- Low input bias current due to bipolar input stage design
Applications
- Medical instrumentation front-end amplifiers
- Precision data acquisition systems
- Photodiode transimpedance amplifiers
Procurement Notes
Verify the suffix CN8 indicates the commercial temperature range and plastic DIP package. Confirm PBF denotes lead-free compliance. Check manufacturer datasheet for exact electrical limits under specific load conditions. Ensure ordering code matches required pinout and thermal specifications.
Selection Notes
Select this component when low noise and high speed are critical simultaneously. Compare against JFET-input op-amps if lower bias current is needed, or CMOS types if lower power is priority. Verify that the 14 MHz bandwidth meets system requirements without excessive gain peaking.
Part Context
This part belongs to the LT137x family of low-noise operational amplifiers. It shares architectural similarities with the LT1376 and LT1377 but differs in bandwidth and noise characteristics. The family is designed for applications requiring high fidelity amplification of small signals.
Replacement Considerations
LT1375CS8#PBF is a direct pin-compatible replacement in SOIC-8 package. LT1375IS8#PBF offers extended industrial temperature range in SOIC-8. Verify package dimensions and thermal dissipation capabilities when substituting.
