I'm looking at using the TL026 in a single-supply application. As far as I can tell, the part really only requires mid-point reference for input biasing; output coupling is AC, and the AGC input is referenced to REF OUT. Further, IN+ and IN- are relatively high-impedance pins (> 10kohm) so the main impedance concern for the input bias network is the input resistor.
So - I'm thinking of using two TL026s in an IF strip (or perhaps just one TL026, depending on noise), using a simple resistive divider, capacitively-decoupled to system ground (negative supply rail). REF OUT would also be referenced to ground through a resistive divider to generate the ~7.2V for the AGC circuit.
Any reason why this shouldn't work?
Thanks -
