Product Overview
The MCP4551-103E/MS is a single I²C Digital Potentiometer with non-volatile memory. It supports potentiometer wiper configuration and EE memory type. The SCL pin is the serial interfaces serial clock pin.
- 8-bit 256 resistors (257 Steps) resistor network resolution
- Four RAB resistances options - 5, 10, 50 and 100kΩ
- Zero to full-scale wiper operation
- 75Ω Typical low wiper resistance
- 50ppm typical (0 to 70°C) absolute (rheostat) low tempco
- 15ppm Typical ratiometric (potentiometer) low tempco
- Non-volatile memory - automatic recall of saved wiper setting
- WiperLock™ technology
- 10 general purpose memory locations
- High-speed read/write to wiper
- Read/write to EEPROM
- Write protect to be enabled/disable
- WiperLock to be enabled/disabled
- Resistor network terminal disconnect feature via terminal control (TCON) register
- Reset input pin
- Hardware write protect (WP) control pin
- Software write protect (WP) configuration bit
- 1.5V typical brown-out reset protection
- 2.5μA typical serial interface inactive current
- High-voltage tolerant digital inputs up to 12.5V
- Internal weak pull-up on all digital inputs, except SCL and SDA
Warnings
ESD sensitive device, take proper precaution while handling the device. Market demand for this product has caused an extension in leadtimes. Delivery dates may fluctuate. Product exempt from discounts.
