Product details

Dual 10kΩ digital rheostat with 256-tap resolution

The MAX5450EUB+ is a dual-channel digital rheostat. Each circuit has 10kΩ end-to-end resistance with 256 wiper tap positions. Wiper resistance is typically 225Ω. Temperature coefficient is 35ppm/°C over -40°C to +85°C.

Package and footprint

Housed in a 10-pin TFSOP/MSOP package (3.00mm width, 0.118" body), the MAX5450EUB+ uses the standard 10-uMAX/uSOP footprint. The supplier device package is listed as 10-uMAX/uSOP, which is Maxim's naming for this MSOP-10 outline. Surface-mount only — no through-hole variant.

Lifecycle and sourcing posture

The MAX5450EUB+ carries an Active lifecycle status with ROHS3 compliance. Sourcing is through independent distribution — we quote this part to order against an RFQ, with current availability and pricing confirmed at quote time.

Frequently asked questions

What is the interface of MAX5450EUB+?

The MAX5450EUB+ uses an Up/Down interface with three control lines: U/D (direction), INC (increment), and CS (chip select). It is a simple pulse-based protocol, not SPI or I²C.

Does MAX5450EUB+ work with 3.3V logic?

Yes, the supply range of 2.7V to 5.5V covers 3.3V and 5V systems. The digital inputs are referenced to the supply rail, so at VDD = 3.3V the logic thresholds are compatible with 3.3V CMOS outputs.

What is the taper of MAX5450EUB+?

The taper is Linear — resistance changes uniformly with the digital code. This suits applications like gain adjustment, offset trimming, and programmable filters where a linear response is needed.
