Potentiometers can be programmed never
to forget
Digitally programmable potentiometers can be permanently set to an initial reading so that no further adjustments are possible
Catalyst Semiconductor has added a new 32-tap device to its extensive family of over 35 digitally programmable potentiometers (DPP) The CAT5126 offers one-time wiper programmability via a simple two-wire serial interface, which enables system designers to set the wiper's value after power-on and also disable the interface to prevent further adjustments

Digitally programmable potentiometers to take over
Catalyst Semiconductor has added two new digitally programmable potentiometer (DPP) ICs to its AE2 (analogue EEPROM) mixed-signal product line.
EEPROM provides more secure MPU supervision
Catalyst Semiconductor has expanded its AE2 analogue EEPROM mixed-signal product strategy with the CAT116x series of microprocessor supervisory circuits with serial 16Kbit EEPROM.
The device also offers the flexibility of not disabling the interface, in which case the system will always "power-on" to the programmed wiper position.
In this mode, users can change the wiper position as necessary for the specific session and the modified value will not be stored.
The CAT5126 digital programmable potentiometer offers end-to-end resistance values of 10kOhm, 50kOhm and 100kOhm and is suitable for LCD screen adjustment; automated calibration; contrast, brightness and volume control; programmable analogue functions; line-impedance matching and mechanical potentiometer replacement in handheld and other space-constrained applications.
The new CAT5126 digital potentiometer comes in 8-lead TDFN (2 x 3mm) and 8-lead MSOP packages and is a pin-for-pin replacement for Maxim's MAX5427 (100kOhm), MAX5428 (50kOhm) and MAX5429 (10kOhm) digital potentiometers.
The CAT5126 digital potentiometer is priced at US $0.53 each in 10,000 piece quantities.
Samples are now available.
Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
