LV4985VH Description
.DataSheet.co.kr Ordering number : ENA1568A Bi-CMOS IC LV4985VH Overview For Portable Electronic Device Use 1.2W × 2ch BTL Power Amplifier The LV4985VH has a 2-channel power circuit amplifier including an electronic volume control built in. It has a function for switching the headphone driver and also has a standby function to reduce the current drain.
LV4985VH Key Features
- 2-cannels BTL power amplifier built-in : Standard output power = 1.2W (VCC = 5V, RL = 8Ω, THD = 10%) Output coupling cap
- Volume function built-in (variable range: 69dB standard), DC voltage control system
- Mute function built-in (shared with VOL-min)
- Standby function built-in (three-value control ⇒ Shared with the second amplifier stop control pin) : Standard standby c
- Second amplifier stop control function built-in (three-value control ⇒ Shared with the standby pin) : Headphone driver s
- Operation supply voltage range : VCC = 4.5V to 5.5V
- Output phase pensation capacitor not necessary
