Description and Introduction

LOW-VOLTAGE 10-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 4/8 ANALOG INPUTS The TLV1544C is a 10-bit, 4-channel analog-to-digital converter (ADC) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Resolution:** 10-bit  
- **Channels:** 4 single-ended inputs  
- **Conversion Time:** 10 µs (max)  
- **Sampling Rate:** Up to 38.5 kSPS  
- **Supply Voltage:** 2.7 V to 5.5 V  
- **Power Consumption:**  
  - 1.5 mW (typical at 3 V)  
  - 4.5 mW (typical at 5 V)  
- **Interface:** 3-wire SPI-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SOIC-16, TSSOP-16  

### **Descriptions:**
- The TLV1544C is a low-power, 10-bit ADC with a built-in 4-channel multiplexer.  
- It operates with a single supply voltage ranging from 2.7 V to 5.5 V, making it suitable for battery-powered applications.  
- The device features a successive approximation register (SAR) architecture for accurate conversions.  
- It includes an on-chip sample-and-hold circuit for stable signal acquisition.  

### **Features:**
- **Low Power Consumption:** Ideal for portable and battery-operated systems.  
- **Wide Supply Range:** Supports operation from 2.7 V to 5.5 V.  
- **SPI-Compatible Interface:** Easy integration with microcontrollers.  
- **Internal Clock:** Eliminates the need for an external clock source.  
- **Auto Power-Down Mode:** Reduces power consumption between conversions.  
- **On-Chip Analog Multiplexer:** Allows selection among four input channels.  
- **Small Package Options:** Available in SOIC and TSSOP for space-constrained designs.  

This information is sourced from TI's official documentation for the TLV1544C.

Application Scenarios & Design Considerations

LOW-VOLTAGE 10-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 4/8 ANALOG INPUTS

Alternative Part Number

  • ADC104S021CIMM --: 10-bit 200kSPS 4-channel SAR ADC with SPI interface, functionally similar to the TLV1544 10-bit 4-channel ADC and pin-compatible in many designs.
  • MCP3204-CI/SL --: 12-bit 4-channel SPI ADC that exceeds the TLV1544 resolution while offering the same serial interface and channel count, suitable as a drop-in upgrade with minor software changes.
  • ADS7844E --: 12-bit 8-channel serial ADC from TI with similar SPI control interface, providing extra channels and higher resolution for designs needing more flexibility than the TLV1544.
