MAX6126AASA21+

Maxim’s MAX6126AASA21+ is a fixed, precision voltage reference IC (now under Analog Devices). It provides a stable reference voltage with low noise and very low drift over temperature, intended to bias ADCs, DACs, and other precision analog circuits. The AASA21+ suffix denotes a specific device variant’s packaging, temperature grade, and RoHS/lot information; exact output voltage, initial accuracy, temperature coefficient, and current consumption are defined in the datasheet for this variant. Typical advantages include tight initial accuracy, low ppm/°C drift, good line/load regulation, low quiescent current, and fast startup. Common applications: precision data acquisition, instrumentation, ADC/DAC reference, sensor conditioning, and calibration sources. For exact specs (Vout, temp range, Iout,max, noise), consult the MAX6126/AASA21+ datasheet.

- Pin count: 8 pins
- Function: MAX6126AASA21+ is a precision fixed-voltage voltage reference (low-drift, low-noise) with an enable/shutdown feature, in an AASA-lead-free 8-pin package (used as a reference for ADC/DAC circuits).

Manufacturer: Maxim Integrated. It is a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits; since 2021, Maxim Integrated operates as a subsidiary/brand of Analog Devices.

Key application areas for MAX6126AASA21+:
- Precision voltage reference for ADC/DAC front-ends in data acquisition and instrumentation
- Calibration and test equipment (digital multimeters, oscilloscopes, lab gear)
- Industrial automation and process control systems needing stable references
- Portable, battery-powered measurement devices (low power, low drift)
- Medical instrumentation requiring high accuracy and stability
- Sensor conditioning and analog front-end bias networks
Notes: typically used where a low-noise, low-drift reference improves overall measurement accuracy.

The MAX6126AASA21+ is packaged in an 8‑pin SOIC (SOP‑8) package, Pb‑free.
