1-07-1999 | The clock in computers and many other electronic systems is normally provided by a simple crystal oscillator. Unfortunately, the electrome...

1-07-1999 | The OPA3682 provides an easy-to-use, broadband fixed gain, triple buffer amplifier. Depending on the external connections, the internal re...

1-07-1999 | The diagram shows how a three-phase sine wave oscillator can be built with a single Type UAF42 state-variable filter and some resistors an...

1-07-1999 | Many applications require a precision voltage source which can be adjusted through zero to both positive and negative output voltage. An e...

1-07-1999 | The precision full-wave rectifier circuit shown in the diagram accepts a.c. inputs of up to ±3 V, yet operates from a single +5 V supply v...

1-07-1999 | The LM56 from National Semiconductor is an accurate, dual-output, low-power thermostat contained in an 8-pin SMD case. It contains a 1.25...

1-07-1999 | The ADM101E is a single-channel RS-232 driver and receiver in the Analog Devices Craft Port™ series, designed to operate from a single +5...

1-07-1999 | The circuit in the diagram uses a synchronous-detection scheme to measure low-level resistances. Other low-resistance-measuring circuits s...

1-07-1999 | More and more lithium-ion batteries are being used in all kinds of appliances. These require a battery charger and for this Maxim’s MAX745...

1-07-1999 | The sensor/monitor shown in the diagram ‘wakes up’ the host system on detection of infra-red (IR) signals. It draws so little supply curre...
