TDA7260 Integrated Circuit

technical specifications of the TDA7260, a Class AB stereo audio amplifier integrated circuit (manufactured by STMicroelectronics):

• Type: Stereo audio power amplifier (2 channels).
• Operating class: AB.
• Output power:
  • 2 x 20W (into an 8 Ω load, with $V_S = \pm 22\text{V}$, $\text{THD} = 10%$).
  • 2 x 13W (into an 8 Ω load, $\text{THD} = 1%$).
• Supply voltage:
  • Dual (split) supply: from $\pm 10\text{V}$ to $\pm 25\text{V}$.
  • Single supply: from $20\text{V}$ to $50\text{V}$.
• Total Harmonic Distortion (THD): 0.05% typical ($P_o = 1\text{W}$, $f = 1\text{kHz}$).
• Signal-to-Noise Ratio (S/N): 100 dB.
• Integrated functions:
  • Mute function (controlled via voltage).
  • Stand-by function.
  • Short-circuit protection (to GND and between outputs).
  • Thermal protection (overtemperature shutdown).
• Package / Case: ZIP-20 (20-pin staggered single in-line, designed for installation on an external heatsink).
