Overview
The ADM660ARU-REEL is a CMOS switched-capacitor voltage converter manufactured by Analog Devices Inc., housed in a 16-lead TSSOP surface-mount package. It functions as a charge pump capable of inverting the input supply to generate a negative rail or doubling it for positive output generation. The device operates with an input voltage range of +1.5 V to +7 V, delivering up to 100 mA of output current. Key electrical parameters include a selectable charge pump frequency of 25 kHz or 120 kHz, a quiescent current of 600 µA, and a typical voltage drop of 0.3 V at a 30 mA load. It requires external capacitors of 2.2 µF or 10 µF depending on the selected frequency.
Feature Summary
- Provides dual functionality to either invert the input supply voltage for negative rail generation or double the input voltage for higher positive output requirements.
- Features a selectable charge pump operating frequency that allows optimization between external capacitor size and static power consumption.
- Utilizes low-power CMOS technology to maintain a low quiescent current while supporting high output currents up to 100 mA.
Applications
- Generating negative supply rails in single-supply systems
- Op amp power supplies requiring bipolar voltages
- Portable computers and handheld instruments
- Remote data acquisition systems
Procurement Notes
Verify the specific suffix 'RU' corresponds to the 16-lead TSSOP package configuration when sourcing. Confirm the '-REEL' designation indicates tape-and-reel packaging suitable for automated assembly processes. Ensure compatibility with the required external capacitor values based on the chosen switching frequency. Cross-reference the manufacturer datasheet for any updates regarding RoHS compliance status and recommended operating conditions.
Selection Notes
Select this component when a single IC solution is needed to create both positive and negative supply rails from a single unipolar source. Consider the 16-lead TSSOP package if board space constraints require a compact surface-mount footprint compared to smaller SOIC options. Evaluate the trade-off between the 25 kHz and 120 kHz frequencies based on available board area for external capacitors versus efficiency requirements.
Part Context
This part belongs to the ADM660 family of CMOS switched-capacitor voltage converters. It serves as a pin-compatible upgrade alternative to legacy devices such as the MAX660, MAX665, and ICL7660. The family includes variants like the ADM8660 which offers a shutdown function but lacks the voltage doubling capability found in the standard ADM660 models.
Replacement Considerations
Public confirmed substitute part numbers include MAX660, MAX665, and ICL7660, which are noted as pin-compatible legacy devices. Verify pinout alignment and electrical specifications against the original design requirements before substitution.
