MAX5387

The MAX5387 is specified over the automotive -40°C to +125°C temperature range and is available in a 14-pin TSSOP package. The MAX5387 dual, 256-tap, volatile, low-voltage linear taper digital potentiometer offers three end-to-end resistance values of 10kI, 50kI, and 100kI. The small package size, low supply operating voltage, low supply current, and automotive temperature range of the MAX5387 make the device uniquely suitable for the portable consumer market, battery backup industrial applications, and the automotive market. Operating from a single +2.6V to +5.5V power supply, the device provides a low 35ppm/°C end-to-end temperature coefficient. The device features an I2C interface.

The features of MAX5387 can be summarized as (1)Dual, 256-tap linear taper positions; (2)single +2.6V to +5.5V supply operation; (3)low < 1A quiescent supply current; (4)10k, 50k, 100k end-to-end resistance values; (5)I2C-compatible interface; (6)power-on sets wiper to midscale; (7)-40°C to + 125°C operating temperature range.

The absolute maximum ratings of MAX5387 are (1)VDD to GND: -0.3V to +6V; (2)H_, W_, L_ to GND: -0.3V to the lower of (VDD + 0.3V)and +6V; (3)all other pins to GND: -0.3V to +6V; (4)continuous current into H_, W_, and L_ MAX5387L: Q5mA / MAX5387M: Q2mA / MAX5387N: Q1mA; (5)continuous power dissipation (TA = +70°C)14-pin TSSOP (derate 10mW/°C above +70°C): 796.8mW; (6)operating temperature range: -40°C to +125°C; (7)junction temperature: +150°C; (8)storage temperature range: -65°C to +150°C; (9)lead temperature (soldering, 10s): +300°C; (10)soldering temperature (reflow): +260°C.
