Description and Introduction

8-bit multiplying D/A converter The **MC1408** is a digital-to-analog converter (DAC) integrated circuit manufactured by **Motorola** (now part of ON Semiconductor). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Resolution:** 8-bit  
- **Output Type:** Current output (requires an external op-amp for voltage output)  
- **Supply Voltage:** Typically **+5V** (logic supply) and **-5V to -15V** (analog supply)  
- **Settling Time:** **300 ns** (typical)  
- **Power Dissipation:** **33 mW** (typical)  
- **Operating Temperature Range:** **0°C to +70°C** (commercial grade)  
- **Linearity Error:** **±0.19%** (full-scale error)  
- **Reference Voltage Range:** **-2V to -18V** (negative reference)  
- **Output Current Range:** **0 to 2 mA** (full-scale)  

### **Description:**
The **MC1408 (DAC0808)** is a monolithic 8-bit digital-to-analog converter designed for high-speed applications. It converts an 8-bit digital input into an analog current output, which can be converted to a voltage using an external operational amplifier.  

### **Features:**
- **Fast Conversion:** High-speed performance with a settling time of **300 ns**.  
- **Wide Reference Voltage Range:** Supports **-2V to -18V** for flexible analog output scaling.  
- **TTL/CMOS Compatible Inputs:** Works with standard logic levels.  
- **Low Power Consumption:** Typically **33 mW**.  
- **Current Output:** Provides **0 to 2 mA** full-scale output.  
- **Monolithic Design:** Ensures reliability and integration ease.  

The **MC1408** is commonly used in **waveform generation, digital control systems, and instrumentation applications**.  

(Note: Some datasheets may refer to this IC as **DAC0808**, a functionally equivalent part from other manufacturers.)
