Packaged in a 5-pin SOT-23-5, this reference occupies minimal board area and is surface-mount compatible. The /NOPB suffix confirms RoHS3 compliance. That means it's safe to qualify into new production BOMs without near-term obsolescence risk.
Initial tolerance is ±0.5% at 25°C. For a 1.8V output, that's ±9 mV maximum error before temperature drift is factored in.
Noise is 20µVp-p over 0.1Hz to 10Hz and 36µVp-p over 10Hz to 10kHz. This is low enough for most 12-bit ADC references without external filtering.
Yes, the /NOPB suffix indicates ROHS3 compliance, meaning it's fully lead-free and meets EU RoHS requirements.
