DS3930E+ Description

Short technical summary and product information.

The DS3930E+ from Dallas Semiconductor is a versatile hex nonvolatile potentiometer IC designed for various applications including RF transceivers, voltage references, and power supply calibration. It integrates six 256-position nonvolatile potentiometers, each group of three forming an equivalent resistance of 16.6k Ω. Additionally, it provides 64 bytes of nonvolatile EEPROM memory and four general-purpose programmable I/O pins.

This device supports a wide supply voltage range from 2.7V to 5.5V, with potentiometer terminals capable of handling 0 to 5.5V independently of VCC. The DS3930E+ utilizes a 2-wire serial interface, allowing up to eight devices to share the same bus. It is housed in a 20-pin TSSOP package and operates within a temperature range of -40°C to +85°C.

Its compact size and nonvolatile nature make it a suitable low-cost replacement for mechanical potentiometers in portable electronics, mobile phones, and fiber optic transceiver modules.
