Specs to look for: When checking for R-to-R, check if spec’ed for input, output or both. You need low noise for the headstage. Use 4 MHz unless speed is an issue. For development, use C datashet from CCS http: Quad, V supply, 20mA output current, output swing: Quad, low noise, rail-to-rail output, 4.
Quad, rail-to-rail output, 2. For these, the input typically includes the minus rail, but only to 1. Prices are for single quantity from Digi-Key.
Single, V supply, 5. Prices listed are for singles, DIP pkg, as of May, more or less. Microchip PIC chip microcontrollers. Non rail-to-rail op-amps can only get to within about 1.
Pre-amp circuits driven by low-noise, ease of use. Op-Amps Considerations are noise matters for audio and high amplification circuitsoffset voltage, slew-rate matters for high frequency and pulse circuitsquiescent current matters for battery-operatedoperating voltage matters for battery operatedsingle or dual supply most modern circuits require single supplyrail-to-rail, output current.
Note lmm7805t resonators do not have tight frequency specs.
For even lower noise, try OP, but you will have to pay more. The MAX is convenient because it is readily available and datashfet no external capacitors. The following table lists datasheeg flash-programmable PIC chip parts. The easiest way to clock a PIC chip is with a ceramic resonator. Good choice for cost, ease-of-use. For example, if you supply a non R-to-R op-amp off 0 and 5 V supplies, the useable output swing will be 1.
Quad, rail-to-rail output, V supply, 1.
Many R-to-R op-amps are R-to-R on the output only. Can find lots of hobby-level info with a good Google search. Jameco has lower prices than Digi-Key, but Digi-Key has wider selection Maxim makes many digital pots, including audio taper. Power amplifier circuits are all about power.
TI has a useful site for comparing op-amps. Lots to choose from.
Maxim makes these in many, many flavors. Cheap, small, and available from Digi-Key. Prices are from Digi-Key unless Jameco number listed.
