FEATURES

?Small, dual-channel, complete PGTIA and AFE solution.

?Small size package: 16-lead LFCSP, 3 mm × 3 mm.

?Four integrated internal gain resistors (RF) per channel:

?Range 0, internal RF0 = 315 Ω

?Range 1, internal RF1 = 3.5 kΩ

?Range 2, internal RF2 = 40.2 kΩ

?Range 3, internal RF3 = 450 kΩ

?Wide input current dynamic ranges from 100 picoamps to milliamps.

?Excellent DC precision:

?Low offset voltage RTI: ±100 μV maximum, 25°C.

?Low input offset voltage drift: ±1.0 μV/°C maximum, ?40°C to +125°C.

?Low switch integrated switch impedance 19 Ω maximum, ?40°C to +125°C.

?Excellent dynamic performance:

?Range 0 settling time 1 μs

?Range 1 settling time 2 μs

?Range 2 settling time 5 μs

?Range 3 settling time 10 μs

?Kelvin-connected architecture eliminates gain error due to switch on-resistance over temperature.

?Single-supply operation: +2.7 V to +5.5 V (dual-supply operation: ±1.85 V to ±2.75 V).

?Wide gain bandwidth product: 8.5 MHz.

?Wide operating temperature range: ?40°C to +125°C.

APPLICATIONS
