Circuit Provides Precision ADC Interface - 08/21/03 - EDN-Design Ideas:
Real-world measurement requires the extraction of weak signals from noisy sources.
High common-mode voltages are often present even in differential measurements. The
usual approach to this problem is to use an op amp or an instrumentation amplifier and
then perform some type of lowpass-filtering to reduce the background noise
level.....(design idea added 12/04) |

electronics, with the ADCs usually organized in groups of 16, 24, 32, and so
on.....(design idea added 1/05) |

Clean Switcher Powers 16 Bit A/D Converters - 07/04/94 - EDN-Design Ideas:
The low-noise switcher in Fig 1 works much like a TV's horizontal-deflection circuit
to provide clean power for a 16-bit A/D converter. In operation, Q3 is a logic-level
gate-drive MOSFET driven by the same 100-kHz square wave that clocks the A/D
converter. When Q3 turns off, the primary of T1 resonates with C3 and flies back to
25V. Energy.....(design idea added 6/06) |

Controller Provides Multiple Alarm Driver Formats - 01/15/98 - EDN-Design Ideas:
DC/DC converters for use inside the telephone handset require operation from the
high-source-impedance phone line. Additionally, the CCITT specifications call for
maximum on-hook power consumption of 25 mA. The dc/dc converter in Figure 1 is
70%-efficient at an input power of 25 mA, providing 5V at 3.4 mA. Controlled, low-peak
switch current ensures that the 48V input line experiences no excessive voltage drops
during switching.....(design idea added 06/06/06) |

DAC and OpAmp Provide Variable Control Voltage - 12/06/01 - EDN-Design Ideas:
Early DACs contained standard R-2R ladder networks, and produced a negative output
voltage. These early DACs, such as the MAX7837/7847 and the MAX523, require both
positive and negative supply rails to accommodate their negative output. With the
transition to single-supply ICs, however, many modern DACs operate with a single
supply rail and an inverted R-2R ladder network.....(design idea added 12/04) |
