I have removed C11 and replaced C14 with 1uF,There is no obvious heat source around the reference chip.

Hi ,
I am using ADR4525 as a 2.5 V reference and ADR130 as 1V reference .I understand the maximum junction temperatures of these parts cannot exceed 150C but I intend to test at 175C for few days
The input voltage for ADR130 is 2.5V from ADR4525. When…
Hello,
I will use ADR4525 as a reference source to an ADC, and would like to know whether I need to put an output buffer or not. What should I consider?
Thanks in advance.

请问用一路ADR4550B(Isc=10mA)分别产生+5V和-5V的基准电压,该两个基准电压后接AD8675的单位增益放大器。产生的VREFPS、VREFPF、VREFNS、VREFNF能否作为16路DAC AD5791的共同基准输入端。 LTSpice无ADR4550的模型,用ADR4525代替仿真。
I am working on an VirtualBench Projects that uses the AD7177-2 32-bit ADC.
Does anyone know any good amplifiers that wil work well With the 32-bit ADC?
I am looking at these parts.
External gain: AD8253
5.00v ref: ADR4550
2.50v ref: ADR4525

Right now the design uses the REF5025 for its initial tolerance and DC stability, but its 1/f noise is actually pretty bad (comparable to the LTC2656's internal reference) so I'm considering either the LTC6655-2.5 or ADR4525 for their low noise esp. at…
