Beskrivning

Dual tandem electronic potentiometer circuit

The TDA1074A is a monolithic integrated circuit designed for use as volume and tone control circuit in stereo amplifiers

Features

* High impedance inputs to both 'ends' of each electronic potentiometer
* Ganged potentiometers track within 0.5dB
* Electronic rejection of supply ripple
* Internally generated reference level available externally so that the control voltage can be made to swing positively and negatively around a well-defined 0V level
* The operational amplifiers have push-pull outputs for wide voltage swing and low current consumption
* The operational amplifier outputs are current limited to provide output short-circuit protection
* Although designed to operate from a 20V supply (giving a maximum input and output signal level of 6V), the TDA1074A can work from a supply as low as 7.5V with reduced input and output signal levels.

* Supply voltage (pin 11) VP typ. 20V
* Supply current (pin 11) IP typ. 22mA
* Input signal voltage (r.m.s. value) Vi(rms) max. 6V
* Output signal voltage (r.m.s. value) Vo(rms) max. 6V
* Total harmonic distortion THD typ. 0.05%
* Output noise voltage (r.m.s. value) Vno(rms) typ. 50uV
* Control range ?a typ. 110dB
* Cross-talk attenuation (L/R) act typ. 80dB
* Ripple rejection (100Hz) a100 typ. 46dB
* Tracking of ganged potentiometers ?Gv typ. 0.5dB
* Supply voltage range VP 7.5 to 23V
* Operating ambient temperature range Tamb -30 to + 80C
