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.
A maximum operating current of 950 μA and a maximum low dropout voltage of 300 mV allow the devices to function very well in portable equipment.
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.
The ADR4525, ADR4540, and ADR4550 are also available in D, which are in 8 lead LCC package, and C grade with a temperature range of 0°C to 70°C. The ADR4525W, available in an 8‑lead SOIC package, is qualified for automotive applications.

EVAL-AD7768-1
AD7768-1 Evaluation Board
Product Detail
The EV-AD7768-1FMCZ evaluation kit features the AD7768-1 24-bit, 256 kSPS analog-to-digital converter (ADC). The EVAD7768-1FMCZ board connects to the USB port of the PC via the EVAL-SDP-CH1Z motherboard. By default, power is supplied from the EVAL-SDP-CH1Z supply, which is regulated to 5 V and 3.3 V to supply the AD7768-1 and support components.
The EV-AD7768-1FMCZ software fully configures the AD7768-1 device register functionality and provides dc and ac time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.
The EV-AD7768-1FMCZ is an evaluation board that allows the user to evaluate the features of the ADC. The user PC software executable controls the AD7768-1 over USB through the system demonstration platform (EVAL-SDP-CH1Z).
