+Stable 6MHz, Low Cost Dual Op Amp
10

11
+The TP09 is CMOS dual RRIO op-amp with low offset, low power and stable high frequency response. They incorporate 3PEAK’s proprietary and patented design techniques to achieve very good AC performance with 6MHz bandwidth, 4.5V/μs slew rate and low distortion while drawing only 500μA of quiescent current per amplifier. The input common-mode voltage range extends 300mV beyond V– and V+, and the outputs swing rail-to-rail.
12
+
13
+The TP09 can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance.
