Product details

2.048 V series reference — 3 µVp-p noise floor

The 3 ppm/°C temperature coefficient means the output shifts less than 0.6 mV over a 100°C swing — enough to keep a 16-bit ADC's reference error below a quarter LSB without external trimming.

±0.05% initial accuracy and 10 mA output

Initial tolerance of ±0.05% gives a 1.024 mV window at 2.048 V, which suits 12-bit systems without calibration. The 10 mA output current can sink or source enough to bias multiple op-amps or a small ADC reference input without a buffer.

Frequently asked questions

What is the noise specification for the REF5020IDRG4?

The noise from 0.1 Hz to 10 Hz is 3 µVp-p. This low noise floor makes it suitable for driving the reference input of a 16-bit SAR ADC without additional filtering.

Can the REF5020IDRG4 replace the REF5020IDR?

The REF5020IDRG4 and REF5020IDR share the same die and electrical specifications. The only difference is the packaging format: the RG4 suffix denotes Tape & Reel, while the IDR suffix is typically Tube. The pinout and footprint are identical, so a direct replacement is possible if the reel format fits the production line.
