- **INL (Integral Nonlinearity)**: ±1 LSB (max)
- **Power Consumption**: 1.5mW (typical at 3V)
- **Operating Temperature Range**: -40°C to +85°C
- **Package**: SOIC-8

### **Descriptions:**
- The TLV5638IDG4 is a dual-channel, 12-bit DAC with an internal reference and a flexible serial interface.
- It includes a power-on-reset circuit to ensure the DAC output powers up at zero scale.
- The device is designed for low-power applications and operates with a single supply voltage.

### **Features:**
- **Dual DAC Channels**: Two independent 12-bit voltage-output DACs.
- **Internal Reference**: 1.024V or 2.048V selectable reference voltage.
- **Low Power Consumption**: Suitable for battery-powered applications.
- **SPI-Compatible Interface**: Supports high-speed serial communication.
- **Rail-to-Rail Output Buffer**: Ensures wide dynamic range.
- **Power-On Reset**: Outputs initialize to zero scale at power-up.
- **Small Package**: SOIC-8 for space-constrained designs.

This DAC is commonly used in industrial control, portable instrumentation, and digital servo control applications.
