AD8594ARZ-REEL7:  运算放大器SOIC-16封装

AD8591AD8592AD8594分别是单路、双路和四路轨到轨输入与输出、单电源放大器,具有250 mA输出驱动电流和省电关断模式。AD8592的每个放大器均具有独立的关断功能。当两个放大器均处于关断模式时,总电源电流降至1 µA以下。AD8591和AD8594均内置一个主关断功能,可将总电源电流降至1 µA以下。在关断模式下,所有放大器输出均处于高阻抗状态。

这些放大器具有极低的输入偏置电流,因而适合积分器和二极管放大应用。输出几乎对任何容性负载均保持稳定。在主动模式下,每个放大器的电源电流小于750 μA。

这些放大器的具体应用包括便携式计算机、便携式电话耳机、音频端口、声卡和机顶盒的音频放大。AD859x系列能够驱动高容性负载,如LCD面板基准电平等。

此外还具有轨到轨输入与输出摆幅能力,因而设计人员可以在单电源系统中缓冲CMOS DAC、ASIC及其它宽输出摆幅器件。

AD8591、AD8592和AD8594的额定温度范围为−40°C至+85°C工业温度范围。AD8591单路放大器提供6引脚小型SOT-23封装。AD8592双路放大器提供10引脚表面贴装MSOP封装。AD8594四路放大器提供16引脚窄体SOIC和16引脚TSSOP两种封装。

The AD8591, AD8592, and AD8594 are single, dual, and quad rail-to-rail, input and output single-supply amplifiers featuring 250 mA output drive current and a power saving shutdown mode. The AD8592 includes an independent shutdown function for each amplifier. When both amplifiers are in shutdown mode, the total supply current is reduced to less than 1 μA. The AD8591 and AD8594 include a single master shutdown function that reduces the total supply current to less than 1 μA. All amplifier outputs are in a high impedance state when in shutdown mode.

These amplifiers have very low input bias currents, making them suitable for integrators and diode amplification. Outputs are stable with virtually any capacitive load. Supply current is less than 750 μA per amplifier in active mode.

Applications for these amplifiers include audio amplification for portable computers, portable phone headsets, sound ports, sound cards, and set-top boxes. The AD859x family is capable of driving heavy capacitive loads, such as LCD panel reference levels.

The ability to swing rail to rail at both the input and output enables designers to buffer CMOS DACs, ASICs, and other wide output swing devices in single-supply systems.

The AD8591, AD8592, and AD8594 are specified over the industrial temperature range (−40°C to +85°C). The AD8591, single, is available in the tiny 6-lead SOT-23 package. The AD8592, dual, is available in the 10-lead surface-mount MSOP package. The AD8594, quad, is available in 16-lead narrow SOIC and 16-lead TSSOP packages.
