1 / 22 page SOC DRV612 RIGHT DAC DAC LEFT Line Driver Gain Programmable -1x to -10x - + - + DRV612 www.ti.com SLOS690B – DECEMBER 2010 – REVISED APRIL 2011 2-Vrms DirectPath ™ Line Driver With Programmable-Fixed Gain Check for Samples: DRV612 1 FEATURES DESCRIPTION The DRV612 is a single-ended, 2-Vrms stereo line 2 • DirectPath ™ driver designed to reduce component count, board – Eliminates Pops/Clicks space and cost. It is ideal for single-supply – Eliminates Output DC-Blocking Capacitors electronics where size and cost are critical design parameters. – 3-V to 3.6-V Supply Voltage • Low Noise and THD The DRV612 does not require a power supply greater than 3.3 V to generate its 5.6-VPP output, nor does it – SNR > 105 dB at –1× Gain require a split-rail power supply. – Typical Vn < 12 μVms 20 Hz–20 kHz Designed using TI ’s patented DirectPath technology, at –1× Gain which integrates a charge pump to generate a – THD+N < 0.003% at 10-kΩ Load negative supply rail that provides a clean, pop-free and –1× Gain ground-biased output. The DRV612 is capable of • 2-Vrms Output Voltage Into 600- Ω Load driving 2 Vms into a 600- Ω load. DirectPath technology also allows the removal of the costly • Single-Ended Input and Output output dc-blocking capacitors. • Programmable Gain Select Reduces Component Count The device has fixed-gain single-ended inputs with a gain-select pin. Using a single resistor on this pin, the – 13× Gain Values designer can choose from 13 internal programmable • Active Mute With More Than 80 dB Attenuation gain settings to match the line driver with the codec • Short Circuit and Thermal Protection output level. It also reduces the component count and board space. • ±8-kV HBM ESD-Protected Outputs Line outputs have ±8 kV HBM ESD protection, APPLICATIONS enabling a simple ESD protection circuit. The DRV612 has built-in active mute control with more • PDP / LCD TV that 80 dB attenuation for pop-free mute on/off • DVD Players control. • Mini/Micro Combo Systems The DRV612 is available in a 14-pin TSSOP and • Soundcards 16-pin QFN. For a footprint-compatible stereo headphone driver, see TPA6139A2 (SLOS700). 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 DirectPath is a trademark of Texas Instruments.
