HT82V733 General Description

HT82V733 is an integrated class AB mono speaker driver contained in an 8-pin DIP/SOP package. The HT82V733 is capable of delivering 400mW output power to an 8W load with less than 10% (THD+N) from a 5V power supply. The very low standby current in shutdown mode contributes to the reduction of power consumption of battery-powered equipments.

HT82V733 Maximum Ratings

Supply Voltage ........................V_SS-0.3V to V_SS+5.5V
Input Voltage............................V_SS-0.3V to V_DD+0.3V

HT82V737 General Description

THT82V737 is a low power consumption stereo DAC with an integrated earphone driver. The device utilizes CMOS technology specially for portable MP3 players, VCD and CD machines.

It converts the 16 bits serial data into an analog output voltage by high precision D/A converter. It can be used with the Japanese input format: time multiplexed, two's complement, MSB first TTL level serial input. With its excellent frequency response characteristics, the HT82V737 provides users a low cost means of implementing high quality audio voltage outputs. It also builds in a class AB stereo driver and some application circuits, thus, requires minimal external components.

The HT82V737 can support low voltage operation at 2.4V so it is very suitable for portable battery powered audio device. A low supply in power down mode current reduces power consumption. It is available in small 16-pin NSOP package.

HT82V738 General Description

The HT82V738 is a high performance audio DAC converter. It provides digital de-emphasis (32, 44.1 and 48kHz), external mute control and adjustment for serial data and clock. The HT82V738 accepts data at audio rates up to 96kHz. It performs within a wide dynamic range, high SNR ratio and has low clock jitter sensitivity. HT82V738 is an ideal DAC for DVD players, MP3 players and set-top box systems. It is also pin-compatible with CS4340.

HT82V738 Maximum Ratings

Supply Voltage ..........................VSS-0.3V to VSS+6.0V
Input Voltage ...........................VSS-0.3V to VDD+0.3V
Storage Temperature ...........................-50 to 125
Operating Temperature ..........................-10 to 70

Note: These are stress ratings only. Stresses exceeding the range specified under "Absolute Maximum Ratings" may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.
