Frequently Asked Questions
How many resistance steps does the AD5235BRU25-EP-RL7 provide and what is its end-to-end resistance?
The AD5235BRU25-EP-RL7 offers 1024 wiper positions across a 25 kOhm end-to-end resistance per channel, yielding approximately 24.4 Ohm resolution per step. This fine granularity is ideal for precision gain trimming and offset calibration in instrumentation amplifier designs.
Does the AD5235BRU25-EP-RL7 retain its settings when power is removed from the circuit?
Yes, the AD5235BRU25-EP-RL7 includes nonvolatile EEMEM storage that preserves the wiper position of both 25 kOhm channels through power cycles. This eliminates the need for host microcontroller recalibration on startup, reducing firmware complexity in embedded designs with tight boot-time constraints.
What interface does the AD5235BRU25-EP-RL7 use and what SPI clock speed does it support?
The AD5235BRU25-EP-RL7 uses an SPI-compatible serial control interface supporting increment, decrement, and direct register write commands. It operates at SPI clock rates up to 50 MHz, enabling fast digital adjustment in real-time signal conditioning loops within industrial and measurement systems.
For which applications is the AD5235BRU25-EP-RL7 enhanced product (EP) grade rating significant?
The EP-grade designation means the AD5235BRU25-EP-RL7 undergoes additional screening for extended reliability, making it suitable for industrial automation equipment, military-adjacent designs, and long-lifecycle instrumentation operating across -40°C to +125°C temperature ranges where standard commercial grade parts may not meet reliability targets.
