Pinout Description
General Pinout Overview
- Package: 44-QFP (Quad Flat Package, 10x10mm body)
- Function: Single-function bipolar analog IC (likely an ADC or measurement IC, given the 3.75-digit resolution).
- Supply Voltage: 7V–11V (single supply).
Pin Categories (Typical for Analog ICs of This Type)
Since the exact part number is unspecified, the following is a generalized breakdown of common pin functions in such devices:
1. Power Supply Pins
- V+ (Pin X): Positive supply voltage (7V–11V).
- V−/GND (Pin Y): Ground reference (single-supply systems may tie this to PCB ground).
- Vref (Pin Z): Reference voltage input (if applicable for ADCs).
2. Analog Interface Pins
- AIN+ (Pin A): Positive analog input (for differential inputs).
- AIN− (Pin B): Negative analog input (or single-ended ground reference).
- AGND (Pin C): Analog ground (isolated from digital ground to reduce noise).
3. Digital Interface Pins
- SCLK/CLK (Pin D): Serial clock input (if SPI/I2C interface is present).
- SDI/DIN (Pin E): Data input (for configuration or daisy-chaining).
- SDO/DOUT (Pin F): Data output (conversion results or status).
- CS/SS (Pin G): Chip select (active-low enable for communication).
4. Control & Configuration Pins
- RESET (Pin H): Hardware reset (active-low or active-high).
- MODE/SEL (Pin I): Mode selection (e.g., sleep, calibration).
- RDY/BUSY (Pin J): Status flag (e.g., conversion complete).
5. Auxiliary Pins
- NC (Pins K...): No-connect (reserved or unused).
- TEST (Pin L): Factory test mode (typically left unconnected).
Thermal & Mechanical
- Exposed Pad (Pin 44 or Center Pad): Thermal pad (may require grounding for heat dissipation).
Notes
- Pin Numbers: Specific assignments depend on the part number (e.g., "44-MQFP" suggests a metric QFP variant).
- Datasheet Critical: For exact pinout, consult the manufacturer datasheet (Harris or legacy Intersil documentation).
- Typical Use Case: This IC is suited for precision analog measurement (e.g., DMMs, instrumentation) with surface-mount design.
