The TS951, TS952 and TS954 family of devices are rail-to-rail BiCMOS operational amplifiers optimized and fully specified for 3 V and 5 V operation.
The TS951 device is housed in the space-saving 5-pin SOT23 package that makes it well suited for battery powered systems. This micropackage simplifies the PC board design because of its ability to be placed in tight spaces (outside dimensions are: 2.8 mm x 2.9 mm).
Key Features
- Rail-to-rail input common mode voltage range
- Rail-to-rail output voltage swing
- Operates from 2.7 V to 12 V
- High-speed (3 MHz, 1 V/µs)
- Low consumption (0.9 mA at 3 V)
- Supply voltage rejection ratio: 80 dB
- Latch-up immunity
- Available in SOT23-5 micropackage, SO8, TSSOP8, SO14, and TSSOP14 packages
