- 40 nV @ 4.17 Hz
- 85 nV @ 16.7 Hz
- Current: 400 µA typ
- Power-down: 1 µA max
- Low noise programmable gain instrumentation amp
- Band gap reference with 4 ppm/°C drift typ
- Update rate: 4.17 Hz to 470 Hz
- 3 differential inputs
- Simultaneous 50 Hz/60 Hz rejection
The device contains a precision low noise, low drift internal band gap reference and can also accept an external differential reference. Other on-chip features include programmable excitation current sources, burnout currents, and a bias voltage generator, the bias voltage generator being used to set the common-mode voltage of a channel to AVDD/2.
The device can be operated with either the internal clock or an external clock. The output data rate from the part is software-programmable and can be varied from 4.17 Hz to 470 Hz.
The part operates with a power supply from 2.7 V to 5.25 V. It consumes a current of 400 µA typical and is housed in 16-lead TSSOP packages.
