are typical examples. In many applications, operating from dual 5V power supplies or single supplies, the TC913ACOA 8-Pin SOIC 0°C to 15 V TC913 offers superior electrical performance, and can +70°C be a functional drop-in replacement; printed circuit TC913ACPA 8-Pin PDIP 0°C to 15 V board rework is not necessary. The TC913’s low offset +70°C voltage error eliminates offset voltage trim TC913BCOA 8-Pin SOIC 0°C to 30 V potentiometers often needed with bipolar and low +70°C accuracy CMOS operational amplifiers. TC913BCPA 8-Pin PDIP 0°C to 30 V The TC913 takes full advantage of Microchip’s +70°C proprietary CMOS technology. Unity gain bandwidth is 1.5 MHz and slew rate is 2.5V/sec.  2001-2012 Microchip Technology Inc.
