Description and Introduction

12-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports The MAX1220BETX+ is a 12-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (formerly Dallas Semiconductor). Below are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 12-bit  
- **Sampling Rate:** Up to 500 kSPS (kilo samples per second)  
- **Input Channels:** 8 single-ended or 4 differential  
- **Supply Voltage:** +5V (analog), +2.7V to +5.25V (digital)  
- **Power Consumption:** 5.5mW (at 500 kSPS, +5V supply)  
- **Interface:** SPI/QSPI/MICROWIRE-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin TSSOP  

### **Descriptions:**
The MAX1220BETX+ is a high-speed, low-power, 12-bit successive approximation register (SAR) ADC. It features an internal track-and-hold (T/H) circuit and a precision reference, making it suitable for applications requiring high accuracy and speed. The device supports both single-ended and differential input configurations.

### **Features:**
- **High-Speed Conversion:** Up to 500 kSPS  
- **Low Power Consumption:** 5.5mW at full speed  
- **Flexible Input Configuration:** 8 single-ended or 4 differential channels  
- **Internal Reference:** 4.096V ±1%  
- **SPI-Compatible Serial Interface:** Easy microcontroller interfacing  
- **Software-Configurable Power Modes:** Includes shutdown mode for power savings  
- **Small Footprint:** 28-pin TSSOP package  

This ADC is commonly used in data acquisition systems, industrial controls, medical instrumentation, and other precision measurement applications.

Alternative Part Number

  • AD1938YSTZ --: Pin-compatible multichannel audio codec with similar 24-bit ADC/DAC architecture and I2S interface, widely used as a drop-in alternative in audio systems.
  • CS42448-CQZ --: Six-channel audio codec offering comparable ADC/DAC performance and serial audio interface, suitable replacement for multichannel audio designs.
  • TLV320AIC3104IRHBR --: Low-power stereo audio codec with integrated ADC/DAC and I2S interface, a common functional substitute when full channel count is not required.
  • AD73322ASTZ --: Similar dual-channel voice-band codec with programmable gain, suitable functional replacement in audio/signal processing designs.
  • TLV320AIC23BIPWR --: Stereo audio codec with integrated ADC/DAC and serial interface, commonly used as a drop-in alternative for similar codec applications.
  • WM8731CLSEFL --: Low-power stereo codec with similar audio interface features, widely available and often used where MAX1220-class codecs are specified.
