Overview
The BD7542SF-E2 is a dual-channel high-voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of +5V to +14.5V (single) or ±2.5V to ±7.25V (dual). Key electrical parameters include a gain-bandwidth product of 600 kHz, a slew rate of 300 mV/µs, and an input bias current of 1 pA. The device features full input and output swing capabilities with a typical DC voltage gain of 95 dB. It is housed in an MSOP-8 package and supports an extended operating temperature range from -40°C to +105°C.
Feature Summary
- High-voltage operation supporting single supplies up to 14.5V
- Full input and output voltage swing capability
- Ultra-low input bias current for minimal loading effects
- Extended industrial temperature range up to +105°C
Applications
- Battery-powered instrumentation circuits
- Industrial sensor signal conditioning
- Portable measurement devices requiring low power consumption
Procurement Notes
Verify the specific suffix 'SF' indicates the MSOP-8 package variant distinct from the SOP-8 version. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified ±2.5V to ±7.25V dual-supply limits if applicable.
Selection Notes
Select this component when high-voltage tolerance and low quiescent current are required alongside full-swing output performance. The MSOP-8 package suits space-constrained designs compared to standard SOP-8 variants. Consider the 600 kHz bandwidth limit for high-frequency applications.
Part Context
This part belongs to the BD7542 family of high-voltage CMOS operational amplifiers. It shares core electrical characteristics with the BD7542F but utilizes a different physical package configuration. The series is designed for applications demanding wide dynamic range and low power dissipation in single-supply environments.
Replacement Considerations
The BD7542F serves as a functional equivalent with identical electrical specifications but utilizes an SOP-8 package instead of MSOP-8. Verify pinout compatibility and thermal requirements before substituting.
