PI5A127UEX is an integrated analog switch based on a CMOS process offering a wide range of analog switch functions. The device integrates two independent bidirectional SPTM switches with a unique combination of high signal integrity and low power consumption for maximum circuit board integration and flexibility. The PI5A127UEX is manufactured on Intersil’s advanced CMOS technology and utilizes carrier modulation to reduce power consumption and improve signal integrity. The PI5A127UEX is available in a variety of package options and is well suited for applications like signal mixing and pairing, antennas, audio feeds, and radio frequency signal routing.

The PI5A127UEX device contains two separate switching paths that are independently controlled by two digital input signals named SEL0 and SEL1. These signals can be used to control a wide range of analog multiplexing operations, including single ended or differential multiplexing and dual channel or four channel multiplexing. The device will also accept two differential input signals and offer either single-ended or differential output configurations. The two switching paths are isolated from each other and will not interfere or compromise signal integrity.

The PI5A127UEX switching paths provide low power consumption and excellent signal fidelity with a unique carrier modulation architecture. This architecture uses an internal transconductance amplifier (OTA) to sense the input signal’s frequency and automatically adjusts the output resistance and power consumption accordingly to minimize power consumption while still providing superb signal integrity. This architecture also minimizes off channel leakage in a differential application by providing very low RINA values.

In terms of operation, the PI5A127UEX features adaptive biasing to optimize performance across the temperature range and allow for multiple speed grades. This allows the device to be used in applications where fast switching speeds are needed as well as in applications where longer switch off times are required for improved signal integrity.

The PI5A127UEX is an excellent choice for many applications including signal mixing, pairing, antennas, audio feeds, and radio frequency signal routing because of its excellent signal integrity and low power consumption. It is available in a variety of package options and is able to provide low on-resistance, low capacitance and excellent signal isolation. Furthermore, its carrier modulation architecture allows for efficient power savings and excellent signal fidelity.
