DESCRIPTION

The DRV602PW is a 2Vrms Pop-less stereo line driver designed to allow the removal of the output dc-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters.

Designed using TI's patented DIRECTPATH™ technology, the DRV602 is capable of driving 2Vrms into a 2.5kΩ load with 3.3V supply voltage. The device has differential inputs and uses external gain setting resistors, that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd order low pass filter to compliment DAC's and SOC converters. The line output of the DRV602 has ±8kV IEC ESD protection. The DRV602 (referred to as the '602) has build-in shutdown control for pop-free on/off control. 

Using the DRV602 in audio products can reduce component count compared to traditional methods of generating a 2Vrms output. The DRV602 doesn't require a power supply greater than 3.3V to generate its 5.6VPP output, nor does it require a split rail power supply. The DRV602 integrates its own charge pump to generate a negative supply rail that provides a clean, pop-less ground biased 2Vrms output.

The DRV602 is available in a 14 pin TSSOP package.

If higher SNR, trimmed DC-offset and external undervoltage-mute functions are beneficial in the application, TI recommends the footprint compatible DRV603 (SLOS617).

Description

The DRV602PWR is a low-power, stereo audio amplifier from Texas Instruments, designed for portable devices and automotive applications. It features DirectPath technology, offering improved audio quality with reduced noise and THD (Total Harmonic Distortion). The amp has differential inputs and can handle 3Vrms output into a 2.5k load with various supply voltages. Its low power consumption makes it suitable for battery-operated devices and energy-efficient systems.

Features

The DRV602PWR features a DirectPath design that eliminates pop/click noises and removes the need for output DC-blocking capacitors. It also offers low noise and THD, with high SNR and low VN. The amplifier supports 3Vrms output into a 2.5k load with various supply voltages, making it suitable for portable audio and automotive applications demanding clear audio quality and power efficiency.

Package

The DRV602PWR has a package type of TSSOP-14, which is a small, surface-mount package.

Pinout

The DRV602PWR is a stereo audio line driver with a TSSOP-14 package. It has a pin count of 14. Functionally, pins are as follows:
VCC (power supply)
GND (ground)
IN+ (non-inverting differential input)
IN- (inverting differential input)
SW (shutdown control)
FB+/FB- (feedback outputs)
OUT+/OUT- (differential output) These pins allow the DRV602PWR to process audio signals, control power state, and provide feedback for system adjustments.

Applications

The DRV602PWR is widely used in portable audio devices (smartphones, tablets), automotive audio systems, gaming consoles, and personal computers for high-quality audio with low power consumption.

Equivalent

The DRV602PWR is a direct-path audio amplifier. Equivalent products from Texas Instruments might include DRV508E or DRV509E, which are also high-quality audio amplifiers with similar characteristics.
