Datasheet Summary with AI

# DRV612 2-Vrms DirectPath™ Line Driver

## Features

️· Single-ended input and output
️· Programmable gain (13 settings)
️· 2-Vrms output into 600-Ω load
️· Eliminates DC-blocking capacitors
️· Active mute with >80dB attenuation
️· Short circuit and thermal protection
️· ±8-kV HBM ESD protection

## Description

The DRV612 is a single-ended, 2-Vrms stereo line driver designed to reduce component count, board space, and cost. It operates from a single supply (3.0-3.6V) and utilizes DirectPath™ technology, integrating a charge pump to generate a negative supply rail for clean, pop-free, ground-biased output.

## Key Electrical Characteristics

️· Supply Voltage (VDD): 3.0-3.6V
️· Output Voltage: 2 Vrms into 600Ω load
️· THD+N: <0.003% @ 10kΩ load, -1x gain
️· SNR: >105dB @ -1x gain
️· ESD Protection: ±8 kV HBM

## Gain Settings

️· Programmable via external resistor
️· Gain values: -2x to -10x (see datasheet for specific values)

## Applications

️· PDP/LCD TV
️· DVD Players
️· Mini/Micro Combo Systems
️· Soundcards

## Pinout

️· Refer to datasheet for detailed pin assignments (including VDD, GND, input, output, gain select, mute).

## Important Notes

️· Requires external charge pump capacitor (1 µF typical) and decoupling capacitors.
️· ESD sensitive - handle with appropriate precautions.
️· Internal undervoltage protection circuitry present.
