Overview

These are tables representing the electrical characteristics of the Linear Technology/Analog Devices LT1999 precision amplifier, in three different configurations:

️· Configuration 1: MP-Grade, temperature range -55°C to 150°C.
️· Configuration 2: Standard, temperature range -55°C < T_A < 150°C.
️· Configuration 1: MP-Grade, temperature range -55°C to 150°C.

Key Differences and Notable Values

I'll organize the comparison by parameters, highlighting the differences.

1. Operating Temperature Range:

️· Configuration 1 & 2: -55°C to 150°C.
️· Configuration 1: -55°C < T_A < 150°C.

2. Supply Voltage (VSENSE)

️· Configuration 1 & 2: This represents the full-scale input sense voltage, meaning the difference between the two input voltages (V+IN - V-IN).
- LT1999-10: -0.35V to 0.35V.
- LT1999-20: -0.2V to 0.2V.
- LT1999-50: -0.08V to 0.08V.

3. Common Mode Input Voltage Range (VCM)

️· Configuration 1 & 2: -5V to 80V. This is the range of common-mode voltages that the amplifier can handle without distorting the output.

4. Input Impedances (RIN(DIFF) and RINCM)

️· RIN(DIFF) (Differential Input Impedance): This indicates how much the input signal is attenuated due to the amplifier's input resistance.
- LT1999-10: 6.4 kΩ.
- LT1999-20: 8 kΩ.
- LT1999-50: 9.6 kΩ.
️· RINCM (Common-Mode Input Impedance): This affects how the amplifier responds to common-mode signals.
- LT1999-10: 5 MΩ.
- LT1999-20: 3.6 MΩ.
- LT1999-50: 20 MΩ.

5. Input Offset Voltage (VOSI)
