n QFN 5mm × 7mm Package The LTC®2496 is a 16-channel (8-differential) 16-bit No
Latency ΔΣ™ ADC with Easy Drive™ technology. The patented sampling scheme eliminates dynamic input current
errors and the shortcomings of on-chip buffering through
automatic cancellation of differential input current. This
allows large external source impedances, and rail-to-rail
input signals to be directly digitized while maintaining …
