- 10pA Max Leakage (<1pA Typ)
- Plug-In, Low-Leakage Upgrades for DG201A/DG202 and DG211JDG212
- Interchangeable Inputs/Outputs
- CMOS and TTL Compatible
- 2pC Typ Charge Injection
- Single- (+10V to-+30V), Bipolar- (:tSV to :t18V), or Unbalanced-(I.e. +12V and -5V} Supply Operation
- 5.25mW Max Power Consumption
- Latchup-Proof Construction
The MAX326/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 MAX326/MAX327 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/MAX327 log1c inputs are CMOS and TTL compatible.
The MAX326/MAX327'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/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.
