LTC1046Inductorless 5V to –5V Converter | PMIC | 2 | Active | The LTC1046 is a 50mA monolithic CMOS switched capacitor voltage converter. It plugs in for the ICL7660/LTC1044 in 5V applications where more output current is needed. The device is optimized to provide high current capability for input voltages of 6V or less. It trades off operating voltage to get higher output current. The LTC1046 provides several voltage conversion functions: the input voltage can be inverted (VOUT= –VIN), divided (VOUT= VIN/2) or multiplied (VOUT= ±nVIN).Designed to be pin-for-pin and functionally compatible with the ICL7660 and LTC1044, the LTC1046 provides 2.5 times the output drive capability.ApplicationsConversion of 5V to ±5V SuppliesPrecise Voltage Division, VOUT= VIN/2Supply Splitter, VOUT= ±VS/2 |

LTC1052Zero-Drift Operational Amplifier | Instrumentation, Op Amps, Buffer Amps | 4 | Active | The LTC1052 and LTC7652 are low noise zero-drift op amps manufactured using an enhanced LTCMOS™silicon gate process. Chopper-stabilization constantly corrects offset voltage errors. Both initial offset and changes in the offset due to time, temperature and common mode voltage are corrected. This, coupled with picoampere input currents, gives these amplifiers unmatched performance.Low frequency (1/f) noise is also improved by the chopping technique. Instead of increasing continuously at a 3dB/octave rate, the internal chopping causes noise to decrease at low frequencies.The chopper circuitry is entirely internal and completely transparent to the user. Only two external capacitors are required to alternately sample-and-hold the offset correction voltage and the amplified input signal. Control circuitry is brought out on the 14-pin and 16-pin versions to allow the sampling of the LTC1052 to be synchronized with an external frequency source.ApplicationsThermocouple AmplifiersStrain Gauge AmplifiersLow Level Signal ProcessingMedical Instrumentation |
