The TDA7056 is an integrated audio amplifier manufactured by Philips (now NXP Semiconductors). Below are its factual specifications, descriptions, and features:

Specifications:

• Type: Mono BTL (Bridge-Tied Load) output amplifier
• Output Power: 3 W (typical at 6 V, 8 Ω, THD = 10%)
• Supply Voltage Range: 3 V to 18 V
• Quiescent Current: 9 mA (typical at 6 V)
• Gain: Fixed at 40 dB
• THD (Total Harmonic Distortion): 0.2% (typical at 1 W, 8 Ω)
• Signal-to-Noise Ratio: 80 dB (typical)
• Operating Temperature Range: -40°C to +85°C
• Package: DIP8 (Dual In-line Package) or SO8 (Small Outline Package)

Descriptions:

• The TDA7056 is a low-voltage mono amplifier designed for battery-powered applications.
• It features a BTL output configuration, eliminating the need for an output coupling capacitor.
• The amplifier has built-in short-circuit and thermal protection.
• It is optimized for minimal external components, making it suitable for compact designs.

Features:

• Low Power Consumption: Ideal for portable devices.
• No External Components Required for DC Gain Setting: Simplifies circuit design.
• Mute Function: Controlled via a logic-level input.
• Short-Circuit Proof: Enhanced reliability.
• Thermal Overload Protection: Prevents damage from overheating.
