Overview
The AD8570ACP-REEL7 is an eight-channel buffer amplifier from the AD8568/AD8569/AD8570 family, manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 4.5 V to 16 V and features rail-to-rail input and output capabilities. The device provides a continuous output current of 35 mA with a peak capability of 250 mA. Key electrical specifications include a maximum offset voltage of 10 mV, a slew rate of 6 V/µs, and a bandwidth of 6 MHz. It is designed for stable operation with capacitive loads up to 1 µF.
Feature Summary
- Eight integrated buffer channels in a single package
- Rail-to-rail input and output signal swing
- High capacitive load drive stability up to 1 µF
- Immunity to output phase reversal under overvoltage conditions
Applications
- LCD monitor reference drivers
- Portable electronic devices
- Communications equipment
Procurement Notes
Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific CP-32-2 LFCSP package marking and date code against the datasheet ordering guide. Ensure proper electrostatic discharge (ESD) handling procedures are followed during storage and assembly due to the sensitivity of the CMOS process.
Selection Notes
Select this part when multiple buffer channels are required in a compact form factor. The AD8570 offers eight buffers compared to two in the AD8568 or four in the AD8569. Consider the 32-lead LFCSP package for thermal performance and space constraints. Verify that the 35 mA continuous current and 6 MHz bandwidth meet the system's drive requirements.
Part Context
This component belongs to the AD856x series of low-cost, single-supply buffer amplifiers built on an advanced high-voltage CBCMOS process. The series includes the AD8568 (two buffers), AD8569 (four buffers), and AD8570 (eight buffers). These devices are optimized for LCD applications requiring high slew rates and significant output drive capability.
Replacement Considerations
Direct functional substitutes within the same family include the AD8568ART-REEL7 and AD8569ARM-REEL, though channel counts differ. For identical eight-channel configurations, verify availability of other AD8570 variants such as AD8570ARU (TSSOP) if package changes are acceptable.
