| Voltage References |
Typically used in transformer secondary side regulation, voltage references provide a stable voltage reference over a wide range of operating conditions. We offer 2.5V and 1.24V internal references with tolerances of 0.25%, 0.5%, 1% and 2%. Adjustable voltage reference can also be configured with use of external components.

| Micropower Voltage References |
Similar to voltage references, Micropower Voltage Reference has lower turn-on current (10uA typ for AS1004-1.2 and 20uA typ for AS1004-2.5. It has greater accuracy at +/- 4mV (0.3% tolerance) and +/- 20mV (0.8% tolerance). These are guaranteed for operation up to 20mA and has very low dynamic impedance.

| Green Mode PWM Controllers |
Green Mode PWM Controllers are more energy saving compared to regular PWM controllers. The high output current drive capability of 1A combined with low start-up current (50uA typical), low operating current (6mA) and low standby power (0.5W) make it an ideal PWM Controller where high efficiency is required.

| Operational Amplifiers |
Operational Amplifiers are available in Dual or Quadruple amplifiers with wide supply voltage range, High gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

| Voltage / Current Amplifiers |
Voltage/current amplifiers are error amplifiers that provide constant voltage/current control in one package. It eliminates the use of separate control amplifier. With an internal reference, the voltage and current loop is guaranteed to stay within limits for your battery charging applications and other requirements for constant source.
