MCP2035

The MCP2035 is an Analog Front-End (AFE) optimized for BodyCom applications. It is a single-channel stand-alone device for low-frequency (LF) signal detection and low-power short range transponder applications, such as BodyCom communications. The device can detect an input signal with amplitude as low as ~1 mVPP, and can demodulate an amplitude-modulated input signal with as low as 8% modulation depth.

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
  • 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 input pin (LF talk-back)
  • Programmable Antenna Tuning Capacitance (up to 63 pF, 1 pF/step)
  • Programmable Output Enable Filter
  • Low Standby Current: 2 µA, typical
  • Low Operating Current: 10 µA, typical
  • Serial Peripheral Interface (SPI™)
  • Industrial Temperature Range: -40°C to +85°C (Industrial)
