TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA2062F
5 Band Graphic Equalizer
TA2062F is 5−band graphic equalizer IC, which have 5 resonance
circuit and an output buffer amplifier.
5 band graphic equalizer for one channel can be formed easily by
externally connecting capacitors and variable resistors which fix
f0 (resonance frequency).
This is suitable for sound field control of car audio system.
Features
· Few external parts
· Boost / cut control range: ±12dB
· Low distortion
: THD = 0.001% (typ.)
(VCC = 8V, f = 1.1kHz, VIN = 1Vrms, flat)
· Low noise
: VNO =3µVrms
(VCC = 8V, Rg =0Ω, flat, BW = 20Hz~20kHz)
· Low harmonic distortion at boost or cut mode
: 2nd and 3rd harmonic distortion are:
2HD, 3HD ≤ 0.01% (typ.)
(VCC = 8V, VIN = 1Vrms, ±6dB boost or cut, f = 20Hz~20kHz)
· Maximum output voltage
: VOM = 2.3Vrms (typ.)
(VCC = 8V, f = 1.1kHz, THD = 1%, flat）
· Operating supply voltage range
: VCC (opr) = 4~16V (Ta = 25°C)
Weight: 0.14g (typ.)
