AS2348中文资料Low Noise, Low Power, 1MHz, RRIO Single / Dual CMOS Operational Amplifiers数据手册Diodes规格书

描述 Description

The AS348/AS2348 are single/dual channels RRIO amplifiers (rail-to-rail input and output), which provide not only maximum output-voltage swing capability but also an extended 300mV common-mode voltage beyond the supply rail. The devices are fully specified to operate from 1.6V to 5.5V single-supply, or ±0.8V and ±2.5V dual-supply applications.

The devices feature a good speed/power consumption ratio, offering 1MHz gain bandwidth while consuming 70μA per channel (typ). They are unity-gain stable for capacitive loads up to 100pF. The low noise density 27nV/√Hz, low input offset voltage 0.5mV and low input offset drift 2μV/°C make them ideal for applications that require precision. With the input bias current is 1pA at room temperature, it is well suitable for low-voltage, low-noise, and low-power applications.

The AS348/AS2348 offer industry-standard packages. The AS348 is available in the SOT25 package, and the AS2348 is offered in the MSOP-8 and SO-8 packages. Temperature is specified for operation: from -40°C to +125°C among all supply voltages. The wide temperature ranges and high ESD tolerance facilitate their use in harsh applications.
