MAX 1232 Microprocessor Monitor The MAX1232CPA is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:
### **Specifications:**
- **Resolution:** 12-bit
- **Sampling Rate:** Up to 100 kSPS (kilo samples per second)
- **Input Voltage Range:** 0V to VREF (external reference required)
- **Supply Voltage:** +5V ±10%
- **Power Consumption:** 5mW (typical)
- **Operating Temperature Range:** 0°C to +70°C
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)
- **Interface:** Parallel (8-bit or 12-bit output)
- **Conversion Time:** 10µs (max)
- **Integral Nonlinearity (INL):** ±1 LSB (max)
- **Differential Nonlinearity (DNL):** ±0.5 LSB (max)
### **Descriptions:**
- The MAX1232CPA is a low-power, high-speed 12-bit ADC with an internal track/hold circuit.
- It requires an external reference voltage (VREF) for operation.
- The device supports both unipolar (0V to VREF) and bipolar (±VREF/2) input ranges with external circuitry.
- It features a parallel interface for easy connection to microprocessors or DSPs.
### **Features:**
- **Low Power Consumption:** 5mW typical at 100 kSPS.
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit.
- **Flexible Input Range:** Supports unipolar and bipolar operation.
- **No Missing Codes:** Guaranteed over the full operating temperature range.
- **Single +5V Supply Operation:** Simplifies power requirements.
- **Parallel Output:** 8-bit or 12-bit selectable for compatibility with different bus widths.
