FEATURES DESCRIPTIO 116d B CMRR Independent of Gain The LTC®2053 is a high precision instrumentation ampli- Maximum Offset Voltage: 10µV fier. The CMRR is typically 116d B with a single or dual 5V Maximum Offset Voltage Drift: 50n V/°C supply and is independent of gain. The input offset voltage Rail-to-Rail Input is guaranteed below 10µV with a temperature drift of less Rail-to-Rail Output than 50n V/°C. The LTC2053 is easy to use; the gain is

Frequently Asked Questions
What are the operating temperature ranges for different packages?
The LTC2053I is -40°C to 85°C, while the LTC2053H handles –40°C to 125°C. The MS8 package can operate from –65°C to 150°C.
Can I use this device in single-supply or dual-supply applications?
Yes, the LTC2053 supports single supply operations as low as 2.7V and can also be used with dual ±5.5V supplies.
Does the unit require an external clock signal?
The standard LTC2053 does not require an external clock. However, the LTC2053-SYNC version has a CLK pin for synchronization to an external clock.
What is the guaranteed Common Mode Rejection Ratio (CMRR)?
For the LTC2053C/LTC2053C-SYNC, the CMRR is typically 113 dB at certain operating ranges.
