The MAX327 quad, single-pole-single-throw (SPST), CMOS analog switches upgrade the DG201A/DG202 and DG211/DG212 with at least 100 times less leakage-the MAX327 have 10pA um 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 gain configurations. And the MAX327 logic inputs are CMOS and TTL compatible. The MAX327"s 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 4-5V and -15V) izes design flexibility. Both parts also feature interchangeable inputs/outputs and "s standard latch up-proof construction. Extremely low power consumption (5.25mW max) makes the MAX327 ideal for portable applications. Other programmable . applications include integrators with long RC time constants, current-to-voltage converters, high-gain amplifiers, and voltage dividers.
