The NTE1507 is an adjustable analog level detector integrated circuit with ten comparators and a reference voltage network. It detects the level of a signal at the analog input and outputs a low logic level. The input voltage steps can be adjusted by the user, and the device can be cascaded. It is suitable for various industrial, consumer, or automotive applications.
The NTE1507 integrated circuit provides ten comparators that digitize an analog input signal in 10‑step (or 100 mV) increments. It features a cascade‑able architecture, open‑emitter outputs capable of sourcing up to 25 mA, and a supply voltage range of 10 V to 35 V, making it suitable for industrial, consumer, and automotive applications such as meters, indicators, and range switching.
The datasheet lists absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics, including threshold voltages for each comparator, output voltage ranges, and temperature limits. A pin‑connection diagram shows the 16‑lead DIP layout and the functions of the cascade, threshold adjust, and analog input pins.
