Overview
The AS1712A-AQFT is a quad, low-offset, high-output CMOS operational amplifier manufactured by ams OSRAM. It delivers up to 200mA of peak output current from a single supply voltage ranging from 2.7V to 5.5V. The device features rail-to-rail input and output capabilities, a gain-bandwidth product of 10MHz, and a high slew rate of 10V/µs. It includes an integrated shutdown feature that drives outputs low when activated. The component operates over the industrial temperature range of -40°C to +85°C and is housed in a TQFN-16 (3x3mm) package.
Feature Summary
- Quad configuration with integrated active-low shutdown control for each pair of amplifiers
- Rail-to-rail input and output stages allowing full signal swing across supply rails
- High output drive capability delivering up to 200mA peak current
- Unity-gain stable operation with capacitive loads up to 100pF
Applications
- Portable and battery-powered audio applications
- Headset and headphone speaker drivers
- Biasing controls for RF power amplifiers
- DAC converter buffers and transformer/line drivers
Procurement Notes
Verify the specific ordering code AS1712A-AQFT against official manufacturer documentation to confirm the TQFN-16 package and quad configuration. Ensure compatibility with the required 2.7V to 5.5V supply range and industrial temperature specifications. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve.
Selection Notes
Select this component for designs requiring high current drive in a compact surface-mount format. The quad architecture supports multiple channels within a small footprint. Verify that the 10MHz bandwidth and 10V/µs slew rate meet the signal processing requirements. Consider the thermal dissipation characteristics of the exposed pad for high-current applications.
Part Context
This part belongs to the AS1710/AS1712 series of high-output-drive operational amplifiers originally developed by austriamicrosystems AG, now operating under ams AG. The series is designed for portable electronics, offering a balance of performance and power efficiency. The AS1712 variant specifically provides four independent amplifiers in a single package.
Replacement Considerations
Consult official manufacturer documentation for confirmed substitute part numbers. Cross-reference pinouts and electrical specifications carefully when considering alternative components.
