Description and Introduction

+2.7V, Low-Power, 4-Channel, Serial 12-Bit ADCs in QSOP-16 The MAX1246ACPE+ is a 12-bit 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:** 4 single-ended or 2 differential  
- **Sampling Rate:** 133ksps (kilosamples per second)  
- **Input Voltage Range:** 0V to VREF (externally adjustable)  
- **Reference Voltage:** External (2.5V to VDD)  
- **Supply Voltage (VDD):** +5V ±10%  
- **Power Consumption:** 2.5mW (at 133ksps), 10µW (power-down mode)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 16-pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The MAX1246ACPE+ is a low-power, 12-bit successive-approximation ADC with an internal track/hold, voltage reference, and serial interface. It is designed for applications requiring high-speed, low-power data acquisition, such as industrial controls, medical instruments, and battery-powered systems.  

### **Features:**  
- **Low Power Consumption:** Operates at 2.5mW (133ksps) with a 10µW shutdown mode.  
- **Flexible Input Configuration:** Supports 4 single-ended or 2 differential inputs.  
- **Internal Track/Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **SPI-Compatible Interface:** Easy interfacing with microcontrollers.  
- **Small Footprint:** Available in a 16-pin PDIP package.  
- **External Reference:** Allows adjustable input range (2.5V to VDD).

Application Scenarios & Design Considerations

+2.7V, Low-Power, 4-Channel, Serial 12-Bit ADCs in QSOP-16

Alternative Part Number

  • AD7873ARUZ --: 12-bit successive-approximation ADC with similar serial interface and throughput, pin-compatible in many designs and widely available.
  • LTC1286CN8 --: 12-bit serial ADC in DIP-8 with comparable sampling rate and single-supply operation, suitable drop-in for many MAX1246 sockets.
  • MCP3204-CI/P --: 12-bit SPI ADC in DIP package with similar resolution and supply range, cost-effective alternative when exact timing is not critical.
