Description and Introduction

IC Voltage-Controlled Amplifiers The THAT2150A is a monolithic dual voltage-controlled amplifier (VCA) manufactured by THAT Corporation. Here are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **THAT Corporation**  

### **Specifications:**  
- **Type:** Dual Voltage-Controlled Amplifier (VCA)  
- **Supply Voltage Range:** ±4.5V to ±18V  
- **Current Consumption:** 5mA typical per amplifier (±15V supply)  
- **Gain Range:** -100dB to +20dB  
- **THD (Total Harmonic Distortion):** <0.01% (typical at 1kHz, +10dB gain)  
- **Noise:** -120dBu (typical, unweighted, 20Hz–20kHz)  
- **Control Voltage Range:** 0V to +3V (for full gain range)  
- **Bandwidth:** 1MHz (typical, -3dB point)  
- **Package:** 16-pin DIP or SOIC  

### **Descriptions:**  
- The THAT2150A is a high-performance, dual-channel VCA designed for professional audio applications.  
- It provides precise gain control with low noise and distortion, making it suitable for mixing, dynamics processing, and automated gain control.  
- Each channel operates independently with matched performance characteristics.  

### **Features:**  
- **Low Noise & Distortion:** Optimized for high-fidelity audio applications.  
- **Wide Gain Range:** Supports both attenuation and amplification.  
- **Independent Channels:** Dual VCAs in a single package with minimal crosstalk.  
- **Flexible Power Supply:** Operates from ±4.5V to ±18V.  
- **Linear dB Gain Control:** Provides accurate gain scaling in response to control voltage.  
- **Industry-Standard Pinout:** Compatible with legacy designs using similar VCAs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

IC Voltage-Controlled Amplifiers

Alternative Part Number

  • SSM2019 --: Low-noise audio preamplifier IC with similar gain and noise performance, commonly used as a drop-in substitute for THAT2150-series parts.
  • INA217 --: Low-noise instrumentation amplifier suited for audio preamp applications, offering comparable noise figure and gain bandwidth.
  • NE5534 --: Widely available low-noise operational amplifier that can serve as a functional substitute in many audio preamp circuits, though noise performance is slightly higher.
  • SSM2142 --: Balanced line driver IC with similar function to the THAT2150A, widely used as a drop-in style alternative in audio output stages.
  • DRV134 --: Balanced audio line driver offering comparable differential output performance and commonly used to replace THAT2150-series parts.
  • INA137 --: Audio differential line receiver/driver with similar signal handling role, suitable when the THAT2150A is used in balanced audio interfaces.
  • SSM2142PZ --: Balanced line driver/audio IC with similar function and performance class, widely available and pin-compatible in many audio designs.
  • DRV134PA --: Balanced audio line driver offering comparable differential output performance, a common substitute in pro-audio circuits.
  • INA137PA --: Audio differential line receiver/driver with similar signal-conditioning role, suitable when exact THAT2150A matching is not critical.
