By the way, I think it should be 16F785. -----Original Message----- From: Chen Xiao Fan Sent: Friday, August 12, 2005 10:47 AM To: 'Microcontroller discussion list - Public.' Subject: RE: [PIC] 16F875 This is an interesting PIC but the OPAMP is too slow to be used for our application (trans-impedance amplifier for photo diode current amplification). According to a VP in Microchip, they are exploring different options of putting an OPAMP to the PICs. This may be the first but there will be more PICs with built-in general purpose OPAMPs. It should be quite okay for normal applications (eg: error amplifier for SMPS, i.e. PID control).

Has anyone played with this one? I'm curious how well the op amp works with the a/d and so on. Could make for a slightly smaller board or fewer parts.
