TB2922HQ
TOSHIBA Bi-CMOS Digital Integrated Circuit
Silicon Monolithic
TB2922HQ
Dual Audio Power Amplifier
Weight: 4.04 g (typ.)
The TB2922HQ is 2ch BTL audio amplifier for TV or home audio
applications.
It includes and the pure complementary P-ch and N-ch DMOS
output stage.
The package is CPP (Compact Power Package).
It is built-in standby function, muting function various kinds of
protectors.
Features
High power output
:
POUT (1)
= 22 W (typ)
(VCC = 18V, RL = 8 Ω, f = 1 kHz, THD = 10%)
:
POUT (2)
= 37W (typ)
(VCC = 16V, RL = 4 Ω, f = 1 kHz, THD = 10%)
:
POUT (3)
= 46W (typ)
(VCC = 26V, RL = 8 Ω, f = 1 kHz, THD = 10%)
:
POUTMAX (1)
= 72W (typ)
(VCC = 26V, RL = 8 Ω, f = 1 kHz, Ｍax Power)
Low distortion ratio : THD
=0.02％ (typ)
Low noise
: Vno = 0.16 μVrms (typ)
(VCC = 18V, RL = 8 Ω, Rg = 0 Ω, BW = 20 Hz~20 kHz)
Low outside parts
Built-in standby switch function (pin 1)
Built-in muting function (pin 6)
Built-in various protection circuits:
Thermal shut down, overvoltage, out to GND, out to VCC, out to out short speaker burned
Operating supply voltage
: VCC (opr) = 9 to 26 V (RL = 8 Ω)
: VCC (opr) = 9 to 18 V (RL = 4 Ω)
Note 1: Install the device correctly. Otherwise, the device or system may be degraded, damaged or even destroyed.
Note 2: The protection features are intended to avoid output short-circuits or other abnormal conditions temporarily.
It is not guaranteed that they will prevent the IC from being damaged.
Exposure to conditions beyond the guaranteed operating ranges may not activate the protection features,
resulting in an IC damage due to output short-circuits.
Note 3: If HBM ESD(condition; 100pF/1.5kΩ) of under -1900V is applied to pin 2 or pin 4 in case that pin3 is GND,
this product may break down.
