Frequency conversion?

Ahh good point on the external interrupt - just didn't think that thought to an end
There is absolutely no need to run an interrupt handler every single time.

I'l look at that diode - I guess it's better than using a resistor?... Read Compelte post

k thanx man, so any idea how i could go about making this substitute for the resistor array??... Read Compelte post

MAX192 ADC schematics?

Fig 18 in the datasheet shows just that.
In general you can directly connect VDD,unless the supply is very noisy,in which case use a 10ohms resistor(which forms a low pass in conjunction with the bypass caps) as specified in the datasheet.
Usually a 0.1uF bypass cap from VDD to Agnd pin(as close to the pins as possible) suffices.... Read Compelte post

hi ved,
if the resistor array in question is being used for pullups of the uC then the SIP used is internally connected as shown in figure. U can create ur own SIP using individual resistors of the same value in a similar configuration.

oops , looks like sunrom and i posted at the same time. ... Read Compelte post

component trouble

Hey guys im making a pcb n cant get some of the parts at the shops in the city, a resistor array & ZIF sockets.... is there any substitute for the resistor array? & can i use a normal ic base instead of the zif socket... the pcb is that of a programmer board of some atmel microcontrollers...
