The LTC2063/LTC2064/LTC2065 are single, dual, and quad low power, zero-drift, 20kHz amplifiers. The LTC2063/LTC2064/LTC2065 enable high resolution measurement at extremely low power levels.

Typical supply current is 1.4µA per amplifier with a maximum of 2µA. The available shutdown mode has been optimized to minimize power consumption in duty-cycled applications and features low charge loss during power-up, reducing total system power.

The LTC2063/LTC2064/LTC2065’s self-calibrating circuitry results in very low input offset (5µV max) and offset drift (0.02µV/°C). The maximum input bias current is only 20pA and does not exceed 100pA over the full specified temperature range. The extremely low input bias current of the LTC2063/LTC2064/LTC2065 allows the use of high value power-saving resistors in the feedback network.

With its ultralow quiescent current and outstanding precision, the LTC2063/LTC2064/LTC2065 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications.

The LTC2063 is available in 6-lead SC70 and 5-lead TSOT-23 packages. The LTC2064 is available in 8-lead MSOP and 10-lead DFN packages. The LTC2065 is available in 14-lead TSSOP and 16-lead 3mm × 3mm QFN packages. These devices are fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.

Product Detail

Demonstration circuit 2837A is a customizable board showcasing the micropower zero-drift op amp LTC2063 (-A option) or LTC2066 (-B option) with shutdown in an SC70 6-pin package. The board is laid out for most common op amp applications and left mostly unstuffed to maximize flexibility for a wide range of applications.

The DC2837A includes the SC70 package op amp, jumpers, unity gain configuration resistors, input lowpass filters, reverse supply protection, and supply bypass capacitors on a small printed circuit board with turrets and SMA connectors for input, output, power and shutdown. The board may be used in split rail or single supply as desired.

The user only needs to furnish external ±2.5V split supplies and an input signal to operate the board. An external shutdown signal can be applied as well to demonstrate the very minimal transient current when starting up the part from shutdown.
