Overview
The AS1713-BTDT is a CMOS difference amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7V to 5.5V with a typical quiescent current of 1.6mA. The device provides a fixed voltage gain of x1, supported by a 10MHz gain-bandwidth product and a 10V/µs slew rate. It includes an active-low enable pin for shutdown mode, reducing supply current to 1nA. The component is housed in an MLPD (2x2mm) 8-pin package.
Feature Summary
- Rail-to-rail input and output stages allow full signal swing across the supply range.
- Integrated resistor trimming ensures high common mode rejection ratio performance.
- Active-low enable pin facilitates low-power shutdown operation with minimal standby current.
- Unity-gain stable design supports capacitive loads up to 100pF without oscillation.
Applications
- Headphone amplifiers requiring ground interference rejection
- Infotainment audio line buffers with ground loop suppression
- Audio differential-to-single-ended conversion circuits
- Instrumentation amplifier back-end stages
Procurement Notes
Verify the ordering code matches AS1713-BTDT exactly. Confirm the package type is MLPD (2x2mm) 8-pin. Ensure RoHS compliance and lead-free status are documented. Check that the datasheet revision aligns with current manufacturing specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed unity-gain difference amplifier is required for audio or sensor signal processing. It is suitable for applications needing rail-to-rail I/O on a single supply. Consider the shutdown feature if power management is critical. Verify that the 10MHz bandwidth meets the system's frequency requirements.
Part Context
The AS1713 is a specialized CMOS difference amplifier designed primarily for audio and instrumentation applications. Manufactured by ams AG, it addresses ground loop interference issues common in long cable connections. The device integrates precision internal resistors to maintain high common mode rejection without external components.
Replacement Considerations
No public confirmed substitute part numbers are available in the documentation.
FAQ
How does the AS1713 handle ground loop interference?
The AS1713 acts as a difference amplifier, treating ground voltage drops as common-mode signals. Its high common mode rejection ratio suppresses these unwanted voltages, preventing them from appearing at the output.
What is the effect of the EN pin on the device operation?
Pulling the EN pin logic low activates shutdown mode, reducing the supply current to 1nA and driving the output to VSS. Pulling it high enables normal operation with a delay of approximately 6µs before the output becomes active.
