Product Description

**GENERAL DESCRIPTION**
The AD5235 is a dual-channel, nonvolatile memory, digitally controlled potentiometer2 with 1024-step resolution, offering guaranteed maximum low resistor tolerance error of ±8%. The device performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and superior low temperature coefficient performance. The versatile programming of the AD5235 via an SPI®-compatible serial interface allows 16 modes of operation and adjustment including scratchpad programming, memory storing and restoring, increment/decrement, ±6 dB/step log taper adjustment, wiper setting readback, and extra EEMEM for user defined information such as memory data for other components,
look-up table, or system identification information.
**FEATURES**
**Dual-channel, 1024-position resolution**
**25 kΩ, 250 kΩ nominal resistance**
**Maximum ±8% nominal resistor tolerance error**
**Low temperature coefficient: 35 ppm/°C**
**2.7 V to 5 V single supply or ±2.5 V dual supply**
**SPI-compatible serial interface**
**Nonvolatile memory stores wiper settings**
**Power-on refreshed with EEMEM settings**
**Permanent memory write protection**
**Resistance tolerance stored in EEMEM**
**26 bytes extra nonvolatile memory for user-defined ****information**
**1M programming cycles**
**100-year typical data retention**
**APPLICATIONS**
**DWDM laser diode driver, optical supervisory systems**
**Mechanical potentiometer replacement**
**Instrumentation: gain, offset adjustment**
**Programmable voltage-to-current conversion**
**Programmable filters, delays, time constants**
**Programmable power supply**
**Low resolution DAC replacement**
**Sensor calibration**
