1. See characterization table for linearity over negative bias voltage.
2. Guaranteed by design.
3. The OTP parameters are selected to cope with a TTC03−474 which offers a resistance of 8.8 kW when heated to a temperature of 110°C.
4. The brown−out circuitry is disabled on versions A & C and operates on versions B & D.
