The LM2903M is a dual differential Independent Voltage Comparator designed to operate from a single power supply over a wide voltage range. It features ±1 to ±18V dual supply operation, 800mA typical low current drain and 25nA typical low input bias current.

• Allows comparison of voltages near ground potential
• Compatible with all forms of logic
• 800µA Low current drain
• 25nA Low input bias current
• ±5nA Low input offset current
• ±1mV Low offset voltage

The LM386N-1/NOPB is a Wide Vin Class-D low Power Audio Amplifier with internal gain designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24mW when operating from a 6V supply, making the LM386 ideal for battery operation.

• Green product and no Sb/Br

The OPA340NA/3K is a single-supply Operational Amplifier optimized for low-voltage. High-speed operation make them ideal for driving sampling analogue-to-digital (A/D) converters. They are also well-suited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analogue (D/A) converters. Single version have identical specifications for design flexibility. The OPA340 series operate on a single supply as low as 2.5V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100k load.

• Rail-to-rail input/output
• 750µA/channel Low quiescent current
• Green product and no Sb/Br
