PS396
Precision, 16-Channel 17V Analog Multiplexer
Features
* Low ON-Resistance (100 Ohms Max.) Minimizes Distortion and Error Voltages * Low Glitching Reduces Step Errors and Improves Settling Times. Charge Injection: 5pC Max. * Dual-Supply Operation (2.7V to 8V) * Single-Supply Operation (+2.7V to +16V) * ON-Resistance Matching Between Channels: <6 Ohms * ON-Resistance Flatness: 10 Ohms (Max.) * TTL/CMOS Logic Compatible (with +5V or 5V supplies) * Fast Switching Speed, tTRANS <250ns * Break-Before-Make action eliminates momentary crosstalk * Rail-to-Rail Analog Signal Range * Low Power Consumption, 10W * Pin Compatible with MAX396 * SOIC and SSOP Packages Minimize Board Area
Description
The PS396 low-voltage, CMOS analog multiplexer offers low ONresistance (100 ohms max.), which is matched to within 6 ohms between switches and remains flat over the specified signal range (10 ohms max). The PS396 is a 16-channel device. The PS396 are fabricated using Pericom's 17V silicon gate process. Design improvements yield extremely low charge injection (5pC max). This multiplexer operates with a single +2.7V to +16V supply or with 2.7V to 8V dual supplies, while retaining CMOS-logic input compatibility and fast switching. The PS396 is pin compatible with the MAX396.

Notes: 2. The algebraic covention, where most negative value is a minimum and most positive value a maximum, is used in this data sheet. 3. Guaranteed by design 4. RON = RON(MAX) - RON(MIN) 5. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. i.e., VNO = 3V to 0V and 0V to -3V. 6. Leakage parameters are guaranteed by desgin. 7. Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation - 20log VCOM/VNO, VCOM = output, VNO = input to off switch. 8. Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
