4-channel High-Efficiency Automotive Audio Power Amplifier IC Featuring Maximum 45W Output: TCB702FNG
Toshiba Electronic Devices & Storage Corporation announced the launch of "TCB702FNG," an addition to its 4-channel high-efficiency linear power amplifiers that meet current market requirements for high efficiency.
With "TCB702FNG," Toshiba has improved on its technology to realize efficiency comparable with a digital high efficiency of class D amplifier in actual operating range (0.5 to 4W). Power consumption is cut by up to 80% of that for a typical class AB amplifier. The new IC’s maximum output is 45W, and the IC is pin-compatible with “TCB701FNG,” the company’s high efficiency linear power amplifier with maximum 50W output.
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.
- Maximum output: 45W×4ch (Vcc=15.2V,RL=4Ω, MaxPower)
- Output noise voltage: 60µVrms (BW=20Hz to 20kHz)
- Supply voltage: 6V to 18V
- Package: P-HSSOP36-1116-0.65-001
Functions and features
- 6V operations
- Full-time error detection for output DC offset voltage
- 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)
