MCP2035
Overview
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. The device can detect an input signal with amplitude as low as ~1 mVPP, and can demodulate an amplitudemodulated input signal with as low as 8% modulation depth.
- 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 input pin (LF talk-back)
- Programmable Antenna Tuning Capacitance (up to 63 pF, 1 pF/step)
- Programmable Output Enable Filter
