AD5252BRU50-RL7 产品详情

GENERAL DESCRIPTION
The AD5251/AD5252 are dual-channel, I2C®, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively. These devices perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors. The parts’ versatile programmability allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components, look-up table, or system identification information.

FEATURES
    AD5251: Dual 64-position resolution
    AD5252: Dual 256-position resolution
    1 kΩ, 10 kΩ, 50 kΩ, 100 kΩ
    Nonvolatile memory1 stores wiper setting w/write protection
    Power-on refreshed with EEMEM settings in 300 µs typ
    EEMEM rewrite time = 540 µs typ
    Resistance tolerance stored in nonvolatile memory
    12 extra bytes in EEMEM for user-defined information
    I2C-compatible serial interface
    Direct read/write access of RDAC2 and EEMEM registers
    Predefined linear increment/decrement commands
    Predefined ±6 dB step change commands
    Synchronous or asynchronous dual-channel update
    Wiper setting readback
    4 MHz bandwidth—1 kΩ version
    Single supply 2.7 V to 5.5 V
    Dual supply ±2.25 V to ±2.75 V
    2 slave address decoding bits allow operation of 4 devices
    100-year typical data retention, TA = 55°C
    Operating temperature: –40°C to +105°C
