MCP2035 - Analog Front-End Device

General Description

The MCP2035 is a single-channel, stand-alone Analog Front-End (AFE) device for low-frequency (LF) signal detection and low-power short range transponder applications, such as BodyCom communications.

Key Features

  • Single Analog Input Pin for Signal Detection.
  • High Input Detection Sensitivity (3 mVPP, typical).
  • High Modulation Depth Sensitivity (as low as 8%).
  • Three Output Type Selections: - Demodulated Data - Carrier Clock - Received Signal Strength Indicator (RSSI).
  • Input Carrier Frequency: 125 kHz, typical.
  • Input Data Rate: 10 Kbps, maximum.
  • 8 Internal Configuration Registers.
  • Bidirectional Transponder Communication via the same i.
