Description and Introduction

Differential Input 16-Bit No Latency Delta Sigma ADC The LTC2433-1IMS is a high-performance, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 24-bit  
- **Input Type:** Differential  
- **Input Voltage Range:** ±VREF  
- **Reference Voltage:** External (up to 5V)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Conversion Rate:** 3.5Hz (default), 6.9Hz (optional)  
- **Noise-Free Resolution:** Up to 23 bits  
- **Integral Nonlinearity (INL):** ±2ppm of FSR (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**  
The LTC2433-1IMS is a low-noise, high-precision ADC designed for applications requiring high-resolution measurements. It features an integrated oscillator, eliminating the need for external components. The device operates with a single supply and includes a flexible digital filter for optimized noise performance.  

### **Features:**  
- **High Accuracy:** 24-bit resolution with no missing codes  
- **Low Noise:** 0.6μVRMS at 3.5Hz  
- **Flexible Output Rate:** Adjustable via pin configuration  
- **No Latency:** Digital filter provides settled data on every conversion  
- **Internal Oscillator:** No external crystal or clock required  
- **Single-Cycle Settling:** Fast response to input changes  
- **SPI-Compatible Serial Interface:** Easy microcontroller interfacing  

This ADC is ideal for precision measurement applications such as weigh scales, temperature sensing, and industrial process control.

Application Scenarios & Design Considerations

Alternative Part Number

  • ADS1240 --: 24-bit delta-sigma ADC with similar resolution and serial interface, suitable as a functional replacement in precision measurement designs.
  • MCP3421 --: 18-bit delta-sigma ADC in a small package with I2C interface, a good alternative when slightly lower resolution is acceptable.
  • AD7190 --: 24-bit sigma-delta ADC with low noise and integrated PGA, offering comparable precision for high-accuracy sensor applications.
  • AD7780BRUZ --: Pin-compatible 24-bit sigma-delta ADC with similar low-power single-channel architecture, suitable replacement for precision measurement applications.
  • MCP3421A0T-E/CH --: Low-power 18-bit delta-sigma ADC in SOT-23, functionally similar for low-speed precision sensing where 18-bit resolution is acceptable.
  • ADS1220IPW --: 24-bit low-power delta-sigma ADC with integrated PGA and SPI interface, offering comparable performance for sensor and instrumentation designs.
