Description and Introduction

12-Bit 300ksps ADCs with FIFO, Temp Sensor, Internal Reference The MAX1230ACEG is a 12-bit, multichannel, successive approximation analog-to-digital converter (ADC) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 3µs (max)  
- **Sampling Rate:** Up to 300ksps  
- **Input Voltage Range:** 0V to VREF (single-ended), ±VREF (differential)  
- **Reference Voltage:** Internal (4.096V) or external (1V to VDD)  
- **Supply Voltage (VDD):** +5V ±10%  
- **Power Consumption:** 8mW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin QSOP  

### **Descriptions:**
- The MAX1230ACEG is a high-speed, low-power, 12-bit ADC with a built-in track/hold circuit.  
- It supports both single-ended and differential input configurations.  
- Features an internal 4.096V reference but allows for an external reference.  
- Includes a serial interface (SPI/QSPI/MICROWIRE compatible) for communication with microcontrollers.  

### **Features:**
- **Low Power:** 8mW typical power consumption.  
- **Flexible Input Configuration:** 8 single-ended or 4 differential channels.  
- **Internal Reference:** 4.096V with low drift (15ppm/°C typical).  
- **High-Speed Serial Interface:** SPI-compatible (up to 5MHz).  
- **On-Chip Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Software-Configurable:** Unipolar/bipolar, single-ended/differential modes.  

This information is based on the manufacturer's datasheet for the MAX1230ACEG.

Application Scenarios & Design Considerations

12-Bit 300ksps ADCs with FIFO, Temp Sensor, Internal Reference

Alternative Part Number

  • AD7490BRUZ --: 16-channel 12-bit SAR ADC with similar SPI interface and throughput, pin-compatible in function and widely available as a direct functional replacement.
  • LTC1859CG --: 8-channel 16-bit ADC with comparable serial interface and performance class, suitable when higher resolution is acceptable in the same application.
  • ADS8344E --: 8-channel 16-bit SAR ADC with SPI interface and similar supply range, a common alternative for MAX1230-class multichannel data acquisition designs.
