Description and Introduction

12-Bit, 200 kSPS ADC, Ser. Out, TMS320 Compatible (up to 10MHz), Single Ch. Pseudo-Differential The TLV2545IDGK is a 12-bit, 200 kSPS analog-to-digital converter (ADC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Resolution:** 12-bit  
- **Sampling Rate:** 200 kSPS (kilo samples per second)  
- **Input Channels:** 4 single-ended or 2 differential  
- **Supply Voltage:** 2.7V to 5.5V  
- **Power Consumption:** 1.5 mW (typical at 3V, 200 kSPS)  
- **Interface:** SPI-compatible serial interface  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSSOP-8 (DGK)  

### **Descriptions:**  
The TLV2545IDGK is a low-power, 12-bit ADC with a fast sampling rate of 200 kSPS. It is designed for precision data acquisition applications and supports both single-ended and differential input configurations. The device operates from a wide supply voltage range, making it suitable for battery-powered and portable applications.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-operated systems.  
- **Flexible Input Configurations:** Supports 4 single-ended or 2 differential inputs.  
- **SPI-Compatible Interface:** Easy integration with microcontrollers.  
- **Internal Reference:** Includes a 2.5V internal voltage reference.  
- **Auto Power-Down Mode:** Reduces power consumption when idle.  
- **Small Form Factor:** Available in an 8-pin VSSOP package.  

This ADC is commonly used in industrial control, medical instrumentation, and portable data logging applications.

Application Scenarios & Design Considerations

Alternative Part Number

  • ADC121S021CIMFX --: 12-bit 200kSPS single-channel SAR ADC in small package, functionally similar to the TLV2545 and pin-compatible in many designs.
  • MCP3201-BI/SN --: 12-bit 100kSPS single-channel SPI ADC with comparable resolution and serial interface, suitable drop-in replacement with minor firmware changes.
  • ADS7816UC --: 12-bit 200kSPS micropower serial ADC offering similar performance and interface, a viable alternative from the same vendor family.
  • MCP3221A5T-I/OT --: 12-bit single-channel I2C ADC with comparable resolution and low power, suitable as a functional substitute where interface flexibility is acceptable.
  • ADS7822U --: 12-bit 200kSPS micropower SAR ADC with similar sampling performance and supply range, a common drop-in style alternative for low-power sensing.
