(2) All grounds on board are tied together, so they should not differ in voltage by more than 0.2 V maximum for any combination of ground signals. By use of a wide trace or ground plane, ensure a low-impedance connection between HPVSS and DVSS. (3) The maximum input frequency should be 50 MHz for any digital pin used as a general-purpose clock. 3.3 Electrical Characteristics At 25°C, AVDD = HPVDD = IOVDD = 3.3 V, SPLVDD = SPRVDD = 3.6 V; DVDD = 1.8 V; fS (audio) = 48 kHz; CODEC_CLKIN = 256 × fS; PLL = Off; VOL/MICDET pin disabled (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT INTERNAL OSCILLATOR—RC_CLK Oscillator frequency 8.2 MHz VOLUME CONTROL PIN (ADC); VOL/MICDET Pin Enabled VOL/MICDET pin configured as volume control 0.5 × Input voltage range (page 0 / register 116, bit D7 = 1 and page 0 / 0 V AVDD register 67, bit D7 = 0) Input capacitance 2 pF Volume control steps 128 Steps 6 ELECTRICAL SPECIFICATIONS Copyright © 2009–2012, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TLV320AIC3110 |
