부품 번호 정의
ADA4807-2 is a dual-channel high-speed, low-noise voltage feedback operational amplifier. ARMZ refers to 8-lead MSOP small-size surface mount package. The suffix R7 represents 7-inch lead-free tape-and-reel packaging dedicated to large-scale automated SMT production.
주요 전기적 성능 매개변수
This dual op amp delivers excellent speed and noise performance optimized for high-speed signal conditioning, data acquisition and high-frequency analog circuits. It operates from single supply voltage ranging from 3 V to 10 V, as well as dual bipolar supplies from ±1.5 V to ±5 V, supporting flexible power architecture design.
The unity-gain bandwidth reaches 180 MHz, accompanied by a fast slew rate of 100 V/μs, enabling rapid response to fast transient input signals. Input voltage noise is only 2.2 nV/√Hz at 1 kHz, which greatly reduces system noise floor for precision small-signal amplification.
Maximum input offset voltage is 0.5 mV, with low offset voltage drift to maintain consistent DC precision amid temperature changes. The device features low total harmonic distortion and outstanding linearity, ideal for driving high-speed ADCs without introducing obvious signal distortion. Internal on-chip frequency compensation ensures unconditional stability at unity gain and all higher closed-loop gain settings.
High common-mode rejection ratio and power supply rejection ratio effectively suppress power supply ripple and common-mode electromagnetic noise in complicated working environments. Each amplifier channel has independent circuitry, minimizing crosstalk between two channels. Quiescent current per amplifier is kept at a moderate level to balance power consumption and dynamic performance.
포장 및 조립 사양
Encapsulated in miniature 8-pin MSOP plastic surface mount package with tiny footprint, which effectively saves PCB layout space for compact analog front-end modules. Moisture Sensitivity Level is MSL3; all reflow soldering operations must be finished within 168 hours once the original vacuum package is opened. Continuous tape reel feeding perfectly matches automatic component placement equipment for mass electronic assembly lines.
환경 및 규정 준수 기준
Industrial operating temperature range covers -40 °C to +125 °C, supporting stable long-term operation in industrial test equipment, portable high-precision measuring instruments, medical analytical devices and communication signal processing modules under harsh temperature fluctuation conditions. Produced with lead-free manufacturing technology, the component complies with global RoHS environmental regulations. The dual-channel integrated layout cuts down component count and simplifies multi-channel analog amplifier circuit design.
