Bi-polar equivalent for LMV771/772

Hi Randy Miller,

         Please check whether this will suit http://www.ti.com/lit/ds/symlink/lmv796-q1.pdf

Hi Randy,

The LMV77x  is a bipolar device, but it is on a low voltage process (5V).

The LMV77x is the low noise version of the bipolar LMV8xx series, targeted for Audio applications.

What is your critical spec, other than supply voltage? Noise? Bias Curent? Speed? Package Size?

There are several possible contenders.

Regards,

Thanks, Paul.  I'm using the 771 as a charge amplifier for a piezoelectric crystal, so bias current is the driving spec.  Frequency of operation is below 200 Hz.  I need to change from a single 5V supply to +-5V supplies.  I'm currently using the SC70-5 package, which is nice.  A dual package is preferable for the new design, as I will need a gain stage after the charge amp.
