MT9162AN1

Telecom Overview

The MT9162AN1 is a single-rail codec integrated circuit manufactured by Microchip Technology, designed for telecom interface applications. It operates on a 4.75V to 5.25V supply voltage with a typical supply current of 4µA. The device features a built-in filter and codec, transmit anti-alias filter, reference voltage, and bias source. It supports one circuit and is available in a 20-SSOP surface mount package. The component functions as a DTMF transceiver IC suitable for signaling applications.

Telecom Feature Summary

• Incorporates a built-in filter and codec with transmit anti-alias filtering capabilities
• Provides integrated reference voltage and bias source for single-rail operation
• Functions as a dual-tone multi-frequency (DTMF) transceiver for signaling

Telecom Applications

• Telecom interface applications
• Signaling applications requiring DTMF transmission
• Voice codec implementations in communication systems

Telecom Procurement Notes

Verify the manufacturer origin, as the part is associated with both Microchip Technology and Zarlink Semiconductor. Confirm the package type is 20-SSOP and ensure the specific revision matches the required DTMF or codec functionality. Cross-reference datasheets from authorized distributors to confirm electrical specifications such as the 4.75V to 5.25V supply range and 4µA current consumption.

Telecom Selection Notes

Select this component for applications requiring a single-rail 5V codec with integrated DTMF transceiver capabilities. Ensure the design accommodates the 20-SSOP surface mount package. Verify that the system requires a built-in anti-alias filter and bias source to simplify external circuitry. Confirm compatibility with standard telecom signaling protocols.

Telecom Part Context

The MT9162AN1 belongs to the family of telecom interface codecs originally developed by Zarlink Semiconductor, now under Microchip Technology. It serves as a specialized IC for voice and signaling processing in telecommunications equipment. The device integrates essential analog front-end functions into a single chip, reducing the bill of materials for digital telephone systems and signaling interfaces.

Telecom Replacement Considerations

Check for direct substitutes within the MT9162 series or compatible Zarlink/Microchip codec families. Verify pinout compatibility and electrical parameter alignment before substitution.
