High CMRR Instrumentation Amplifier (Schematic and Layout) design for biomedical applications

on
Instrumentation amplifiers are intended to be used whenever acquisition of a useful signal is difficult. IA’s must have extremely high input impedances because source impedances may be high and/or unbalanced. bias and offset currents are low and relatively stable so that the source impedance need not be constant. Balanced differential inputs are provided so that the signal source may be referenced to any reasonable level independent of the IA output load reference. Common mode rejection, a measure of input balance, is very high so that noise pickup and ground drops, characteristic of remote sensor applications, are minimized.Care is taken to provide high, well characterized stability of critical parameters under varying conditions, such as changing temperatures and supply voltages. Finally, all components that are critical to the performance of the IA are internal to the device. The precision of an IA is provided at the expense of flexibility. By committing to the one specific task of

6Watt Hi Fi Audio Amplifier using TDA 2613

on
A 6 watt Hi Fi Audio amplifier TDA2613 . TDA2613 is an integrated hi-fi amplifier IC from Philips Semiconductors. HF is on / off test, click, short-circuit proof, thermal protection and is offered in 9-pin single in line package of plastic.

In the given circuit, TDA2613 connected to the control of a supply. Capacitor C4 is the DC input, while decoupler capacitors C5, C6 are the filters of the power supply. Audio is fed to the non-inverting input through capacitor C4. Inverting input and Vp / 2 pins of the IC are connected along and grounded through capacitor C3. Capacitor C2 couples the speaker to the output of integrated circuits and the network comprising capacitor C1 and resistor R1 improved high frequency stability.
