8-Lead LCC Pin Configuration GENERAL DESCRIPTION The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ADR4550 devices are high precision, low power, low noise voltage references featuring ±0.
02% B, C, and D grade maximum initial error, excellent temperature stability, and low output noise.
This family of voltage references uses an innovative core topology to achieve high accuracy while offering industry-leading temperature stability and noise performance.
The low, thermally induced output voltage hysteresis and low long-term output voltage drift of the devices also improve system accuracy over time and temperature variations.
The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/ADR4550 series of references are each provided in an 8-lead SOIC and are available in a wide range of output voltages, all of which are specified over the extended industrial temperature range of −40°C to +125°C...
