Description and Introduction

16-Bit, 85ksps ADC with 10µA Shutdown The MAX195BEWE+ is a high-performance, 16-bit analog-to-digital converter (ADC) manufactured by Maxim Integrated (formerly Dallas Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 16-bit  
- **Sampling Rate:** 100 kSPS (kilo-samples per second)  
- **Input Voltage Range:** ±10V, ±5V, 0 to +10V (software selectable)  
- **Power Supply:** ±5V (analog), +5V (digital)  
- **Power Consumption:** 200mW (typical)  
- **Integral Nonlinearity (INL):** ±2 LSB (max)  
- **Differential Nonlinearity (DNL):** ±1 LSB (max)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Total Harmonic Distortion (THD):** -100dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin Wide SOIC  

### **Descriptions:**
- The MAX195BEWE+ is a successive-approximation register (SAR) ADC with high accuracy and low noise.  
- It includes an internal track-and-hold (T/H) circuit, eliminating the need for an external sample-and-hold amplifier.  
- The device supports both unipolar and bipolar input ranges, configurable via software.  
- It features a parallel interface for easy integration with microprocessors and DSPs.  

### **Features:**
- **16-Bit Resolution with No Missing Codes**  
- **Flexible Input Ranges (±10V, ±5V, 0 to +10V)**  
- **Low Power Consumption (200mW typical)**  
- **Internal T/H Circuit**  
- **Parallel Data Output Interface**  
- **Software-Configurable Unipolar/Bipolar Operation**  
- **Guaranteed Performance Over Full Temperature Range (-40°C to +85°C)**  
- **Single +5V Digital Supply Operation**  

The MAX195BEWE+ is commonly used in high-precision data acquisition systems, industrial automation, and instrumentation applications.

Application Scenarios & Design Considerations

16-Bit, 85ksps ADC with 10µA Shutdown

Alternative Part Number

  • AD7870AQ --: Pin-compatible 12-bit successive-approximation ADC with similar speed and parallel interface, widely used as a MAX195 substitute.
  • ADS7805U --: 12-bit 100 kSPS sampling ADC in SOIC with comparable accuracy and parallel output, suitable drop-in replacement in most designs.
  • LTC1278CN --: 12-bit 400 kSPS ADC with similar parallel interface and reference architecture, offering higher speed as an upgrade path.
  • AD7705BNZ --: 16-bit sigma-delta ADC with similar resolution and serial interface, widely available and pin-compatible in function for many precision measurement designs.
  • LTC2400CS8 --: 24-bit no-latency delta-sigma ADC offering higher resolution than the MAX195, suitable as an upgrade in precision low-speed acquisition applications.
  • ADS1115IDGSR --: 16-bit delta-sigma ADC with I2C interface, low power and easy integration, a practical modern substitute for general-purpose 16-bit conversion needs.
