NJM2770R-TE1 - Brand New New Japan Radio IC Chips
-
Description
The NJM2770R-TE1 is a high-power and low-voltage audio power amplifier with standby function. It is designed with a differential output type, eliminating the need for external coupling capacitors. The closed loop gain can be adjusted using two external resistors. It provides a typical output power of 250mW at 3V-supply and 8ohm-load, and 400mW at 4.5V-supply and 16ohm-load. The standby current is only 0.1µA, making it suitable for various applications including PCS, codeless telephones, speaker amplifiers for hands-free systems, and especially cellular phones.
