AS2376M8-13

Overview

The AS2376M8-13 is a dual precision operational amplifier manufactured by Diodes Incorporated, housed in an MSOP-8 surface-mount package. It features a gain bandwidth product of 5.5 MHz and operates within a supply voltage range of 2.2V to 5.5V. The device exhibits low noise characteristics with a spectral density of 9.5nV/√Hz at 1kHz and a maximum input offset voltage of 25μV. Quiescent current per amplifier is typically 760μA, with a maximum of 950μA. It supports rail-to-rail input and output capabilities and functions reliably across an ambient temperature range of -40°C to +125°C.

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the tape and reel packaging format containing 2,500 units per carrier. Confirm that the MSOP-8 package variant matches the required PCB footprint dimensions. Ensure compliance with RoHS and lead-free requirements as specified in the manufacturer's documentation before finalizing procurement orders.

Selection Notes

Select this component when high precision and low noise are critical alongside moderate bandwidth requirements. The post-package trimming ensures tight offset voltage specifications compared to standard chopper-stabilized amplifiers. Consider the thermal resistance characteristics of the MSOP-8 package for heat dissipation in dense layouts. Verify that the capacitive load driving capability meets the application needs without additional nulling resistors.

Part Context

This part belongs to the AS2376 family of low-noise, low quiescent current precision operational amplifiers. The 'M8' designation specifically identifies the MSOP-8 package type, distinguishing it from the SO-8 variant. The '-13' suffix indicates the standard tape and reel packaging configuration used for automated assembly processes.

Replacement Considerations

An automotive-compliant version of this component is available under the separate datasheet designation AS2376Q. Designers requiring AEC-Q100 qualification should verify if the standard AS2376M8-13 meets their reliability standards or if the Q-series part is necessary.

FAQ

How does the AS2376 achieve low offset voltage without restricting bandwidth?

Unlike many op amps that use chopper stabilization which limits bandwidth, the AS2376 achieves low offset through post-package trim, allowing it to retain its full 5.5 MHz bandwidth.

What is the recommended method for driving large capacitive loads with this amplifier?

To drive loads larger than 250 picofarads, insert a nulling resistor (RS) in series with the load capacitor. The suggested value for this resistor is between 10Ω and 20Ω.
