ANALOG DEVICES ADA4806-1ARJZ-R7 运算放大器, 105 MHz, 1个放大器, 160 V/µs, 2.7V 至 10V, SOT-23, 8 引脚
Product Details
The ADA4806-1 is a high speed, voltage feedback, rail-to-rail output, single operational amplifier with three power modes: full power mode, sleep mode, and shutdown mode. In full power mode, this amplifier provides a wide bandwidth of 105 MHz at a gain of +1, a fast slew rate 160 V/μs, and excellent dc precision with a low input offset voltage of 125 μV maximum and an input offset voltage drift of 1.5 μV/°C maximum, while consuming only 500 μA of quiescent current. Despite being a low power amplifier, the ADA4806-1 provides excellent overall performance, making it ideal for low power, high resolution data conversion systems.
For data conversion applications where minimizing power dissipation is paramount, the ADA4806-1 offers a method to reduce power by dynamically scaling the quiescent power of the ADC driver with the sampling rate of the system by switching the amplifier to a lower power mode between samples.
Sleep mode reduces the amplifier quiescent current to 74 μA and provides a fast turn-on time of only 0.45 μs, enabling the use of dynamic power scaling for sample rates approaching 2 MSPS. For additional power savings at lower samples rates, the shutdown mode further reduces the quiescent current to only 2.9 μA.
The ADA4806-1 operates over a wide range of supply voltages and is fully specified at supplies of 3 V, 5 V and ±5 V. This amplifier is available in a compact, 8-lead SOT-23 package and is rated to operate over the industrial temperature range of −40°C to +125°C.
