Introduction The LT1991 precision op amp is a superb choice for
The LTC2630’s combination of a 12-bit DAC and low-drift amplifying or attenuating the DAC output to achieve a
integrated reference in a tiny SC-70 package has proven desired output range because it requires no precision
popular for a wide variety of applications. Two new DACs, external resistors. Its integrated, precision resistors are
the LTC2631 and LTC2640, tak……
