Programmable negative rail for analog bias
The ICL7664BCSA is a programmable negative voltage regulator from the * series, designed to generate a regulated negative output from a positive input rail. Its primary application is in analog signal chains — op-amp supplies, DAC/ADC reference rails, and sensor bias circuits — where a clean negative voltage is needed without a separate transformer or charge-pump inverter.
Active status and compliance note
Note that this part is RoHS non-compliant — it is not exempted but intentionally manufactured with lead-bearing terminations, which may restrict its use in markets with full RoHS enforcement unless a specific exemption applies.
Bulk packaging for low-volume or prototyping runs
Shipped in Bulk format, the ICL7664BCSA is suited for engineering samples, prototyping, or short-run production where tube or tray handling is preferred over tape-and-reel.
