AN231E04 dpASP

AN231E04The AN231E04 dpASP Dynamically Reconfigurable Analog Signal Processor

The AN231E04 is the exciting, market driven parent device for Anadigm’s 3rd generation solutions. The AN231E04 operates from a 3.3volt power supply, consumes less current yet has twice the signal bandwidth of its predecessor.

New Features

  • Offset nulling, an internal routine started by a configuration command from a host microprocessor and available at any time.
  • All internal OpAmp input offset voltages can be reduced from a few milli-volts to less than 250 micro-volts, the routine will temporarily break any existing signal paths for a period of 70msec (assuming a 16MHz ACLK); By default this auto-nulling routine is added into all primary configurations.
  • Complex I/O cells employing an uncommitted differential Amplifier which can be accessed by the user and wired using an external component to perform a variety of function: eg, buffering, level shifting, filtering (Rauch topology) for either input or Output signals, alternatively this I/O cell can be used for sample and hold, gain, bypass wiring or digital I/O.
  • Size and power have been reduced dramatically, the device power consumption is now typically 125mW and the device is pakaged in a 7x7x0.85mm QFN package. (RoHS compliant)
  • Addition dynamic control features have been added to allow easy control of the circuit update (re-configuration) and monitoring using digital pins.
  • With dynamic re-configurability, you can program the AN231E04 to implement multiple analog functions and/or to adapt 'on-the-fly' to maintain precision operation despite system degradation and aging.   
  • With analog functions defined by software, the analog subsystem can be controlled using C-code automatically generated by AnadigmDesigner®2.
  • Dynamic re-configuration enables functions never possible before, eg. two 5-pole filters can be have three parameters swept independently or simultaneously; Gain, corner frequency and Q-factor.
