- Extremely low input bias current of 0.01pA typical
- Internally compensated for unity gain stability without external components
- Output short circuit protection included
Applications
- Photodiode amplifiers
- High performance portable instruments
- Data acquisition systems
- Active filters
- Picoammeters
Procurement Notes
Verify the specific suffix 'SAL' indicates an 8-pin Small Outline Plastic Dip (SOIC) package with lead-free (RoHS compliant) construction. Confirm the operating temperature range matches the application requirements, as this specific package variant supports 0°C to +70°C. Ensure static control procedures are followed during handling due to ESD sensitivity.
Selection Notes
Select this component when designing circuits requiring high source impedance compatibility and minimal power consumption. The rail-to-rail operation makes it suitable for low-voltage battery-powered systems. Consider the 0.01pA input bias current for applications involving capacitive sensors or charge integrators where leakage must be minimized.
Part Context
This part belongs to the ALD2731 family of dual precision CMOS operational amplifiers. The 'A' designation typically refers to offset voltage specifications, while 'SAL' denotes the SOIC-8 lead-free package. It shares pinout compatibility with industry standard µA741 and ICL7611 types, facilitating direct replacement in legacy designs.
Replacement Considerations
Compatible replacements include ALD2731APAL (PDIP package), ALD2731ASA (legacy leaded SOIC), and ALD2731ADA (CERDIP package). Verify that substitute parts maintain the same rail-to-rail input/output characteristics and micropower specifications.
