Analog Devices Inc. AD5252BRU1-RL7
- Part Number:
- AD5252BRU1-RL7
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3021024-AD5252BRU1-RL7
- Description:
- IC DCP DUAL 1K 256POS 14TSSOP TR
- Datasheet:
- AD5252BRU1-RL7
Description
The AD5251/AD5252 are dual-channel, I²C, nonvolatile memory, digitally controlled potentiometers with 64/256 positions, respectively. They perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors. Their 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.
Features
AD5251: Dual 64-position resolution
AD5252: Dual 256-position resolution
1 kΩ, 10 kΩ, 50 kΩ, 100 kΩ
Nonvolatile memory stores wiper setting with 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 kn 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, T, = 55°C
Operating temperature: -40°C to 105°C
Applications
Mechanical potentiometer replacement
General-purpose DAC replacement
LCD panel V.com adjustment
White LED brightness adjustment
RF base station power amp bias control
Programmable gain and offset control
Programmable voltage-to-current conversion
Programmable power supply
Sensor calibrations
