Frequently Asked Questions
What is the temperature coefficient of LT1021DCN8-5#PBF and how does it affect reference accuracy over temperature?
The LT1021DCN8-5#PBF has a maximum temperature coefficient of 20 ppm/°C. Over a 100 °C industrial temperature range of -40 °C to +85 °C, this corresponds to a maximum reference voltage drift of 10 mV from the nominal 5 V output, ensuring that downstream 12-bit or 16-bit ADCs maintain sub-LSB reference error across the full operating range.
Can the LT1021DCN8-5#PBF directly drive a reference load of 10 mA without an output buffer stage?
Yes. The LT1021DCN8-5#PBF provides a maximum output current of 10 mA, which is sufficient to supply the reference input of most precision ADCs and DACs directly without an external buffer op-amp. This simplifies circuit design, reduces component count by 1 op-amp and associated passives, and eliminates buffer-introduced offset and noise in precision measurement applications.
When is LT1021DCN8-5#PBF preferred over a bandgap reference such as the REF02 for an 8-bit DIP prototype design?
The LT1021DCN8-5#PBF is preferred when the design requires a 5 V reference with 20 ppm/°C maximum drift in a through-hole 8-pin DIP form factor that can be inserted into a socket for easy replacement during calibration. Its 10 mA output current and tight temperature coefficient outperform many standard REF02-class devices, making it a more precise choice for prototype instrumentation requiring less than 2 LSB reference error at 12-bit resolution.
