The MAX326 quad, single-pole-single-throw (SPST) .. CMOS analog switches upgrade the DG201A/DG202 and DG211/DG212 with at least 100 times less leakage-the MAX326 have 10pA maximum leakage while the DG201 A/DG202 have 1000pA and the DG211/DG212 have 5000pA. Low leakage currents support high system accuracy and make the devices useful for switching into high impedan­ces. such as large-value feedback resistors in closed­ loop gain configurations. And the MAX326 log1c inputs are CMOS and TTL compatible.

The MAX326's low charge_injection (2pC typ) minimizes signal error. Operation from single supplies (+10V to +301/), dual supplies (-:t.5V to -:t.18V), and unbal­anced combinations (i.e. +12V and -5V, or +5V and -15V) maximizes design flexibility. Both parts also feature inter­changeable inputs/outputs and Maxim's standard latchup-proof construction.

Extremely low power consumption (5 25mW max) makes the MAX326 ideal for portable applications. Other programmable -applications include integrators with long RC time constants, current-to-voltage con­verters, high-gain amplifiers, and voltage dividers.
