HA1377 is a power amplifier integrated circuit produced by Hitachi, Japan. There are two sets of power amplifier circuits on a silicon chip with high output power. Under 13.2V power supply voltage, 5.8W output power can be obtained when 4Ω load THD = 10% . When BTL is connected, 17W output power can be obtained under the same conditions as above. Suitable for portable, desktop mono and stereo dual-channel recorders and other audio equipment, using 12-lead single in-line plastic packaging structure, the shape is shown in Figure 1.
 Circuit characteristics: [1]. The harmonic distortion is small, not more than 1% at 100Hz-10kHz. [2]. There is a surge protection circuit inside the circuit. [3]. There is a thermal cut-off protection circuit inside. [4]. Few external components. |
| Typical application circuit and electrical parameters: Figure 2 shows the typical application circuit of HA1377 in dual-channel operation. Figure 3 shows the typical application circuit of BTL connection. Table 1 shows the electrical parameters of HA1377 and Table 2 shows the limit parameters. |

| Instructions for use: |
| HA1377 and HA1377A are the same package form, with the same external dimensions and pin function arrangement. The electrical parameters and application diagrams are also the same and can be interchanged under normal circumstances. The difference is: HA1377A can be used for BTL connection, but HA1377 can not be used for BTL connection. |
