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 DG201A/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 again configurations. And the MAX326 logic inputs are CMOS and TTL Compatible. The MAX326 low charge injection (2pc typ) minimizes signal error. Operation from single supplies (+10V to +30V). dual supplies (±5V to ±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-proff 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 voltages dividers.
