TA8220H Overview
is made only on the single channel.) 1. Voltage gain adjustment This IC has the amplifier constructions as shown Fig.1. The pre-amp (amp1) is provided to the primary stage, and the input voltage is amplified by the flat amps, amp3 and amp4 of each channel through the phase amp (amp2).
TA8220H Key Features
- Low thermal resistance: θj-T = 1.5°C / W (infinite heat sink)
- Low distortion ratio: THD = 0.04% (typ.) (VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV = 50dB)
- Low noise: VNO = 0.30mVrms (typ.) (VCC = 13.2V, RL = 4Ω, GV = 50dB, Rg = 0Ω, BW = 20Hz~20kHz)
- Built-in stand-by function (with (4)pin set at low, power is turned off.): ISB = 1µA (typ.)
