SAN JOSE, Calif. – March 21st, 2011 – Nuvoton Technology Corporation today announced three audio amplifiers in its line of emPowerAudio ™ solutions. The ISD810X is a family of audio Class-AB amplifier capable of driving a resistive speaker load with up to 2Wrms output power.  These amplifiers include current limiting and a chip enable pin with extremely low standby current and excellent pop-and-click performance.

ISD810X can be configured with either single-ended or differential inputs. Internal resistors set the device to have 20dB gain, and with external resistors any gain less than this can be achieved.  The device is unity gain stable, including use with external feedback resistors and external capacitors as may be optionally used for implementing simple filtering functions. In addition, it has a superior fast start up response time, which is suitable for the fast MCU response.

ISD810X family is based on high-fidelity audio amplifier architecture delivering 100dB Signal to Noise Ratio (SNR) and THD of < 0.1% @ 0.8W with a 5V supply ISD810X’s wide 2V to 6.8V supply voltage offers a flexibility of power source from Li-Ion batteries or a combination of 2 to 4 alkaline batteries.   More significantly, ISD810X audio amplifier family operates at a low current consumption and at an industry leading standby current, which greatly reduces power consumption and extends battery life in the applications of toy and portable devices.

ISD8101 is capable of driving an 8Ω load with up to 1.5Wrms output power, and able to operate at 2.4V to 6.8V supply voltage. Differential Analog inputs can be used in ISD8101.

ISD8102 is capable of driving a 4Ω load with up to 2Wrms output power, and able to operate at 2V to 6.8V supply voltage. Headphone sense mode is implemented to control either Single-Ended Output or BTL output.

ISD8104 is capable of driving a 4Ω load with up to 2Wrms output power, and able to operate at 2V to 6.8V supply voltage. Differential Analog inputs can be used in ISD8104.

Availability, Pricing

The ISD8101 is available in an 8-SOP (with or without thermal ex-pad) package. The packaged part is priced below US$0.3 in quantities of 5000. Samples and evaluation boards are available today.

The ISD8102/ISD8104 is available in an 8-SOP (with thermal ex-pad) package. The packaged part is priced below US$0.5 in quantities of 5000. Samples and evaluation boards are available today.
