Overview
The LM2902AT14-13 is a quad operational amplifier manufactured by Diodes Incorporated, housed in a TSSOP-14 package. It features internally compensated high-gain amplifiers with very low input offset voltage (1mV typical). The device operates from a single supply of 3V to 36V or dual supplies of ±1.5V to ±18V. Key electrical parameters include a unity gain bandwidth of 700kHz, a large DC voltage gain of 100dB, and a supply current of 700µA independent of the supply voltage magnitude.
Feature Summary
- Features very low input offset voltage for precision applications
- Operates from wide single or split power supply ranges
- Includes internal frequency compensation for stability
- Input common-mode voltage range includes ground potential
Applications
- Transducer amplifiers
- Active filters
- DC gain blocks
Procurement Notes
Verify the specific ordering suffix 'T14-13' corresponds to the TSSOP-14 package and tape & reel packaging configuration as defined in the manufacturer's ordering information. Confirm that the 'A' grade designation matches the required low input offset voltage specifications for your design constraints before finalizing procurement.
Selection Notes
Select this component when a quad amplifier configuration is required with low offset voltage characteristics. Ensure the application utilizes a single-ended or split power supply within the specified 3V to 36V range. Consider the TSSOP-14 package dimensions and thermal impedance if operating near maximum temperature limits.
Part Context
This part belongs to the LM2902/LM2904 series of dual and quad operational amplifiers produced by Diodes Incorporated. The series is characterized for operation across an extended temperature range of -40°C to +125°C. The 'A' suffix denotes a version with tighter input offset voltage specifications compared to the standard non-A version.

FAQ
What is the input common-mode voltage range?
The input common-mode voltage range includes ground (0V) up to VCC-1.5V at +25°C.
Is the supply current dependent on the supply voltage?
No, the supply current drain is essentially independent of the magnitude of the power supply voltage over the operating range.
