It operates from a single 2.7V supply while still supporting 5V applications. The current consumption is 750A per op amp. The LTC2052, despite its miniature size, features uncompromising DC performance. The typical input offset voltage and offset drift are 0.5V and 10nV/C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB. The input common mode voltage ranges from the negative supply up to 1V from the positive supply. The LTC2052 also has an enhanced output stage capable of driving loads as low as 1k to both supply rails. The open-loop gain, loaded with 1k, is in excess of 140dB. The LTC2052 also features a 1.5VP-P DC to 10Hz noise and a 3MHz gain bandwidth product. , LTC and LT are registered trademarks of Linear Technology Corporation.

Note 2: These parameters are guaranteed by design. Thermocouple effects preclude measurements of these voltage levels during automated testing. Note 3: The LTC2052C, LTC2052HVC is guaranteed to meet specified performance from 0C to 70C and is designed, characterized and expected to meet these extended temperature limits, but is not tested at - 40C and 85C. The LTC2052I, LTC2052HVI is guaranteed to meet the extended temperature limits. Note 4: The bias current measurement accuracy depends on the proximity of the negative supply bypass capacitors to the device under test. Because of this, only the bias current of channels A and B is 100% tested to the data sheet specifications. The bias current of channels C and D is also 100% tested to relaxed limits; however their values are guaranteed by design to meet the data sheet limits. 3 LTC2052 PACKAGE DESCRIPTIO 0.015 0.004 x 45 (0.38 0.10) 0.007 - 0.0098 (0.178 - 0.249) 0.016 - 0.050 (0.406 - 1.270) 0 - 8 TYP * DIMENSION DOES NOT INCLUDE MOLD FLASH.
