―Power consumption up to 90% lower than general class AB amplifier―

TOKYO–(BUSINESS WIRE)–Toshiba
Electronic Devices & Storage Corporation
today announced a new
4-channel high-efficiency linear power amplifier “TCB701FNG,” that meets
current market requirement for high efficiency. Sample shipments will
start in January, 2018.


With “TCB701FNG,” the company has improved on its technology to realize
efficiency comparable with a digital high efficiency, class D amplifier
in actual operating range (0.5 to 4W). Power consumption is cut by up to
90% of that for a typical class AB amplifier.

The new amplifier also includes a self-diagnosis function with I2C
bus control that can diagnose errors and contribute to a suitable set
design by changing the detection setting for gain or time constants. It
also includes full-time error detection of output DC offset voltage,
which can quickly detect abnormal output offset voltage and prevent
speaker burnout, improving set reliability.

 

Main specifications

Part number   TCB701FNG
Maximum output

49W×4ch (Vcc=15.2V, RL=4Ω, MaxPower)

Supply voltage 6V to 18V
Total harmonic distortion 0.01% (Pout=0.4W)
Output noise voltage 60μVrms (BW=DIN_AUDIO)
Power consumption

Up to 1/10 lower than a typical class AB amplifier
(supply
voltage=14.4V in case of 1W output)

Functions and features

• 6V operations
• Full-time error detection for output DC
offset voltage
• Anti-high frequency noise
• I2C
bus control allows diagnosis of errors such as cross output
connection.
• Various detections are selectable from two or
more settings, such as a gain, mute time constants and temperature.

Can be used as both a power amplifier and line output amplifier.

Various built-in protection circuits (output cross connection,
over voltage, and low voltage)

Package   P-HSSOP36-1116-0.65-001
