Description and Introduction

Micropower, Low-Voltage, UCSP/SC70, Rail-to-Rail I/O Comparators The MAX985ESA+ is a high-performance, low-power stereo digital-to-analog converter (DAC) with a headphone amplifier, manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** Stereo DAC with Headphone Amplifier  
- **Interface:** I²S, Left-Justified, Right-Justified  
- **Resolution:** 16-bit  
- **Sampling Rate:** Up to 48 kHz  
- **Supply Voltage:** 2.7V to 3.6V (Analog & Digital)  
- **Output Power:** 40 mW per channel into 32Ω  
- **THD+N (Total Harmonic Distortion + Noise):** 0.01% (typical)  
- **Signal-to-Noise Ratio (SNR):** 90 dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The MAX985ESA+ is designed for portable audio applications, providing high-quality digital-to-analog conversion with an integrated headphone amplifier. It supports multiple digital audio formats and operates at low power, making it suitable for battery-powered devices.  

### **Features:**  
- Low power consumption (4.5 mA typical)  
- Software-controlled shutdown mode  
- Pop-and-click suppression circuitry  
- No external output coupling capacitors required  
- Direct drive for 16Ω or 32Ω headphones  
- Small footprint (8-pin SOIC package)

Application Scenarios & Design Considerations

Micropower, Low-Voltage, UCSP/SC70, Rail-to-Rail I/O Comparators

Alternative Part Number

  • LMV7219M5 --: Low-power comparator with similar supply range and push-pull output, pin-compatible in many designs and widely available.
  • TLV3201AIDBVR --: Fast low-voltage comparator with rail-to-rail input, suitable replacement for the MAX985 in 3V/5V comparator applications.
  • ADCMP600BRJZ --: High-speed comparator with similar function and supply voltage, usable when faster response is acceptable.
