OPA388-Q1数据手册TI中文资料规格书

描述 Description

The OPA388-Q1 precision, operational amplifier is an automotive, low-noise, fast-settling, zero-drift device that provides rail-to-rail input and output operation. Excellent ac performance, combined with only 0.25µV of offset and 0.005µV/°C of drift over temperature, make the OPA388-Q1 a great choice for driving high-resolution, analog-to-digital converters (ADCs) with high accuracy. Zero-crossover technology minimizes any offset change over the common-mode range. The combination of low drift and very low 1/f noise allow the OPA388-Q1 to monitor and detect faulty conditions without compromising signal integrity.

The OPA388-Q1 is available in the SOT23-5 package. The device is specified over the industrial temperature range of –40°C to +125°C.
