Dual Independent 256-Tap Precision Digipot
Dual-channel linear digital potentiometer, each channel with 256 adjustable taps, 100kΩ end resistance ±20% tolerance. Support 3-terminal potentiometer & 2-terminal rheostat two working modes; INL ±0.5LSB, DNL ±0.25LSB for high-precision resistance trimming.
Non-Volatile EEPROM Memory Core Advantage
Internal EEPROM non-volatile storage keeps wiper setting during power off, recovers preset resistance within 100μs after power on. Avoid repeated manual calibration, ensure consistent circuit performance for mass production equipment.
Universal I2C Interface & Wide Power Compatibility
Standard I2C serial bus up to 400kHz, configurable chip address for multi-chip cascading. Compatible with single supply 2.7V~5.5V digital circuit and dual ±2.25V~±2.75V analog audio/signal circuits, match mainstream MCU hardware design.
Ultra Miniature X2QFN-14 Tiny Packaging
14-pin X2QFN(Micro QFN) only 2.0mm×2.0mm footprint, far smaller than TSSOP-14 version, greatly save PCB layout space for miniaturized devices. MSL1 moisture sensitive level, lead-free RoHS & REACH compliant, tape&reel 3000pcs standard reel for high-volume SMT assemblyTexas Instruments.
Low Drift & Wide Miniature Application Coverage
Ultra-stable 4ppm/°C ratio temperature coefficient, built-in 2kV HBM ESD protection and low-power shutdown mode, operating range -40℃~+85℃. Perfect for wearable electronics, portable handheld devices, stereo audio volume, dual sensor calibration, mini adjustable power and compact test instruments, direct substitute for small dual mechanical potentiometers.
