Prezentare generală a produsului
ADN2850 dual-channel, non-volatile memory, digitally controlled resistor with a 1024-step resolution, offering a guaranteed maximum low resistor tolerance error of ±8%. The device performs the same electronic adjustment function as a mechanical rheostat with enhanced resolution, solid-state reliability, and superior low-temperature coefficient performance. The versatile programming of this 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. Application includes SONET, SDH, ATM, Gigabit Ethernet, DWDM laser diode driver, optical supervisory systems, mechanical rheostat replacement, instrumentation gain adjustment, program filters, delays, time constants, and sensors calibration.
- Maximum resolution is 10bit (VDD=2.7V to 5.5V, VA=VDD, VB=VSS, -40°C <lt/> TA <lt/> +85°C)
- Minimum resistor tolerance is -8% (code=full scale, -40°C <lt/> TA <lt/> +85°C)
- Single-supply power range from 2.7 to 5.5V (VSS=0V, -40°C <lt/> TA <lt/> +85°C)
- Minimum output logic high (SDO, RDY) is 4.9V (RPULL-UP=2.2Kohm to 5V)
- Typical negative supply current is −2µA (VIH=VDD or VIL=GND, -40°C <lt/> TA <lt/> +85°C)
- Current monitoring configurable function
- SPI-compatible serial interface, non-volatile memory stores wiper settings
- Power-on refreshed with EEMEM settings, permanent memory write protection
- 16-lead frame chip scale package [LFCSP]
- Temperature range from -40°C to +85°C
