MAX308CPE

The MAX308CPE is a precision, monolithic, CMOS analog multiplexer (mux) from Analog Devices, offering an 8:1 single-ended configuration. It boasts low on-resistance of less than 100 Ohms, matched to within 5 Ohms between channels and remaining flat over the specified analog signal range (7 Ohms max). This device also provides low leakage over temperature, with NO-off leakage current less than 5nA at +85°C, and fast switching speeds with transition times less than 250ns.

Fabricated using Maxim's improved 44V silicon-gate process, the MAX308CPE offers extremely low charge injection (less than 10pC) and guarantees electrostatic discharge protection greater than 2000V. It operates with a single +5V to +30V supply or bipolar ±5V to ±20V supplies, while retaining TTL/CMOS-logic input compatibility. These improved parts are plug-in upgrades for the industry-standard DG408, DG409, DG508A, and DG509A.

The MAX308CPE is supplied in a 16-pin DIP package suitable for through-hole mounting. Its operating temperature range is 0°C to 70°C. Key electrical characteristics include a typical channel resistance of 1.5 Ohms, crosstalk of -92dB at 100kHz, and low power consumption of less than 300µW.

Applications for the MAX308CPE include sample-and-hold circuits, automatic test equipment, heads-up displays, guidance and control systems, military radios, communications systems, battery-operated systems, PBX/PABX, and audio signal routing.
