The LTC1540IMS8#PBF is an ultralow nano-power single Comparator with built-in reference. The comparator features include less than 0.6µA supply current over the commercial temperature range, a 1.182V±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2 to 11V supply or a dual ±1 to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. The comparator input operates from the negative supply to within 1.3V of the positive supply. The comparator output stage can continuously source up to 40mA. By eliminating the cross-conducting current that normally occur when the comparator changes logic states, power supply glitches are eliminated.

• Reference output drives 0.01µF capacitor
• Input voltage range includes the negative supply
• Reference output sources Up to 1mA
• 60µs Propagation delay with 10mV overdrive
• No crowbar current
• 40mA Continuous source current

• LTADV Part marking

The LM2900N is a general purpose quadruple Norton Operational Amplifier consist of four independent, high-gain frequency-compensated Norton operational amplifiers that were designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies is also possible. The low supply current drain is essentially independent of the magnitude of the supply voltage. These devices provide wide band-width and large output voltage swing.

• Wide range of supply voltages, single or dual supplies
• Wide bandwidth
• Large output voltage swing
• Output short-circuit protection
• Internal frequency compensation
• Low input bias current
