What are the key features of TC7660EPA?

Switched-capacitor voltage inverter operating from 1.5 V to 10 V input
Generates a negative output voltage equal to the magnitude of the positive input supply
Requires only 2 external capacitors — no inductors needed
Low quiescent current suitable for battery-powered analog circuits
8-pin DIP package for easy prototyping and through-hole PCB assembly

What is TC7660EPA used for?

The TC7660EPA is commonly used to generate a negative supply rail for op-amps, ADC reference circuits, and LCD bias supplies from a single positive voltage source. It is a popular choice in portable instruments, data acquisition systems, and audio circuits where a split ±5 V supply is needed without a dedicated negative regulator. Its simple 2-capacitor design makes it a cost-effective solution in space-constrained analog designs.

Frequently Asked Questions

What input voltage range does the TC7660EPA support and what output polarity does it produce?

The TC7660EPA accepts a positive input from 1.5 V to 10 V and inverts it to produce an equivalent negative output voltage. For example, a 5 V input results in approximately -5 V output, enabling a split-supply rail from a single positive source with just 2 external capacitors.

How does TC7660EPA simplify negative rail generation compared to an inductor-based inverting converter?

Unlike inductor-based inverting converters, the TC7660EPA uses switched-capacitor topology requiring only 2 external capacitors and no magnetics. This reduces component count, eliminates EMI from inductor switching, and shrinks the 8-pin DIP footprint, which is especially valuable in analog instrumentation and audio designs.

Which procurement considerations apply when buying TC7660EPA for a high-volume analog design?

The TC7660EPA has a factory lead time of approximately 8 weeks in PDIP-8 package. Designers specifying it in volume production should verify RoHS compliance (JESD-609 code e3) and consider whether the SOT-23 or SOIC alternatives fit automated SMT assembly better to reduce per-unit cost.
