TL082 is a Wide Bandwidth Dual JFET Input Operational Amplifier.
TL 082 General Description
These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage (BI-FET II™ technology). They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents.
TDA1054M is produced by SGS Thomson and is a preamplifier with ALC ( Automatic Level Control ) for cassette recorders.
TDA 1054M is a monolithic integrated circuit in a 16-lead dual in-line plastic package. The functions incorporated are:
- Low noise preamplifier
- Automatic Level Constrol system ALC
- High gain equalization amplifier
- Supply voltage rejection facility SVRF
TDA1054 is intended as preamplifier in in cassette tape recorders and players, compressor and expander, dictaphones, Hi-Fi preamplifiers and in wire diffusion receivers.
Here you have the TDA1054 specifications – tda1054 datasheet
The TDA1514A integrated circuit is a hi-fi power amplifier for use as a building block in radio, tv and other audio applications. The TDA 1514 circuit is totally protected, also has a mute function that can be arranged for a period after power-on with a delay time fixed by external components. The device is intended for symmetrical power supplies but an asymmetrical supply may also be used.
TDA1514 Features:
Complete LM358 datasheet specifications. The LM358 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
