Description
Single supply rail-to-rail amplifiers are commonly used in analog systems. In some cases it is important to have an amplifier output that drives very close to GND (i.e. a few microvolts). However, no amplifier can inherently drive this close to GND. This TI Precision Design shows a simple design modification that allows most standard single supply rail-to-rail amplifiers to drive very close to GND.
Features
- Drives output to true GND
- Avoids output swing limitations near GND using pull-down
- Single-Supply Solution
