10 / 53 page  TLV320AIC3254 SLAS549D – SEPTEMBER 2008 – REVISED NOVEMBER 2014 www.ti.com 8.6 Electrical Characteristics, Bypass Outputs At 25°C, AVDD, DVDD, IOVDD = 1.8V, LDOIN = 3.3V, AVDD and DVDD LDO disabled, fs (Audio) = 48kHz, Cref = 10µF on REF pin, PLL disabled unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT ANALOG BYPASS TO HEADPHONE AMPLIFIER, DIRECT MODE Load = 16 Ω (single-ended), 50pF; Input and Output CM = 0.9V; Headphone Output on LDOIN Supply; Device Setup IN1_L routed to HPL and IN1_R routed to HPR; Channel Gain = 0dB Gain Error –0.8 dB Idle Channel, IN1_L and IN1_R ac-shorted to Noise, A-weighted(1) 3 μVRMS ground THD Total Harmonic Distortion 446mVrms, 1kHz input signal –89 dB ANALOG BYPASS TO LINE-OUT AMPLIFIER, PGA MODE Load = 10k Ω (single-ended), 56pF; Input and Output CM = 0.9V; LINE Output on LDOIN Supply; Device Setup IN1_L routed to ADCPGA_L and IN1_R routed to ADCPGA_R; Rin = 20kΩ ADCPGA_L routed to LOL and ADCPGA_R routed to LOR; Channel Gain = 0dB Gain Error 0.6 dB Idle Channel, 7 μVRMS IN1_L and IN1_R ac-shorted to ground Noise, A-weighted(1) Channel Gain = 40dB, Input Signal (0dB) = 5mVrms 3.4 μVRMS Inputs ac-shorted to ground, Input Referred (1) All performance measured with 20kHz low-pass filter and, where noted, A-weighted filter. Testing without such a filter may result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter removes out-of-band noise, which, although not audible, may affect dynamic specification values. 10 Submit Documentation Feedback Copyright © 2008–2014, Texas Instruments Incorporated Product Folder Links: TLV320AIC3254 |
