AD74111 datasheet



This is Mono Audio Codec.

The AD74111 is a front-end processor for general-purpose audio and voice applications. It features a multibit – A/D conversion channel and a multibit – D/A conversion channel. The ADC
channel provides >67 dB THD+N and the DAC channel provides >88 dB THD+N, both over an audio signal bandwidth. The AD74111 is particularly suitable for a variety of applications where mono input and output channels are required, including audio sections of digital video camcorders, portable personal audio devices, and telematic applications. Its high quality performance also makes it suitable for speech and telephony applications such as speech recognition and synthesis, and modern feature phones. An on-chip reference voltage is included but can be powered down and bypassed by an external reference source if required. The AD74111 offers sampling rates that, depending on MCLK selection and MCLK divider ratio, range from 8 kHz in the voiceband range to 48 kHz in the audio range. The AD74111 is available in a 16-lead TSSOP package option and is specified for the automotive temperature range of –40°C to +105°C.

TDA2050 Datasheet PDF – 32W Hi-Fi Audio Amplifer – ST

Part Number: TDA2050


Package: Pentawatt Vertical Type

Manufacturer: ST Microelectronics




The TDA2050 is a monolithic integrated circuit in Pentawatt package, intended for use as an audio class AB audio amplifier. Thanks to its high power capability the TDA2050 is able to provide up to 35W true rms power into 4 ohm load @ THD = 10%, VS =  ±18V, f = 1KHz and up to 32W into 8ohm load @THD = 10%, VS = ±22V, f = 1KHz.

Moreover, the TDA 2050 delivers typically 50W music power into 4 ohm load over 1 sec at VS= 22.5V, f = 1KHz. The high power and very low harmonic and crossover distortion (THD = 0.05% typ, @ VS = ±22V, PO = 0.1 to 15W, RL=8ohm, f = 100Hz to 15KHz) make the device most suitable for both HiFi and high class TV sets.




1. High output power (50 W music power IEC 268.3 rules)

2. High operating supply voltage (50 V)

3. Single or split supply operations

4. Very low distortion

5. Short-circuit protection (OUT to GND)

6. Thermal shutdown

Absolute maximum ratings :

1. Supply voltage : Vs = ±25 V

2. Input voltage : Vi = Vs

3. Differential input voltage : Vi = ±15 V

4. Output peak current (internally limited) : Io = 5 A

5. Power dissipation at Tcase = 75 °C : Ptot = 25 W

6. Storage and junction temperature : Tstg, Tj = -40 to 150 °C
