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.
