ADM660ANZ

Overview

The ADM660ANZ is a charge pump DC-DC switching regulator manufactured by Analog Devices Inc., housed in an 8-pin PDIP package. It operates with an input voltage range of 1.5V to 7V and provides a single fixed output configured as either -Vin or 2Vin. The device delivers a maximum output current of 100mA and supports switch frequencies of 25kHz and 120kHz. It functions within a temperature range of -40°C to 85°C.

Feature Summary

• Charge pump topology for generating inverted or doubled voltage outputs
• Fixed output configuration options including negative inversion and voltage doubling
• Single output channel capability with up to 100mA drive current

Applications

• General purpose power supply inversion
• Voltage level shifting in low-power circuits
• Dual polarity supply generation from single source

Procurement Notes

Verify the specific suffix 'ANZ' confirms the 8-PDIP through-hole package variant, distinct from surface-mount versions like ARZ. Confirm RoHS3 compliance status and check for lead-free soldering requirements during assembly. Ensure the ordering quantity matches the standard tube packaging format associated with this package type.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or specific board layout constraints. Compare against the ARZ variant if surface mount space is limited. Verify that the 100mA output current meets the load requirements and that the 25kHz/120kHz frequency options suit the external capacitor selection for ripple performance.

Part Context

This part belongs to the ADM660 family of charge pump inverters. It shares core electrical specifications with the surface-mount ADM660ARZ but differs in physical mounting style. The family is designed for simple, cost-effective voltage conversion without requiring inductors.

FAQ

What are the available output configurations?

The ADM660ANZ can be configured to provide either a negative voltage equal to the input (-Vin) or a positive voltage double the input (2Vin).

Does this device use synchronous rectification?

No, the ADM660ANZ does not feature synchronous rectification; it utilizes a standard charge pump architecture.
