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, 10µW
• Pin Compatible with MAX396
• SOIC and SSOP Packages Minimize Board Area
Description
The PS396 low-voltage, CMOS analog multiplexer offers low ON-
resistance (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.
Applications
• Data Acquisition Systems
• Audio Switching and Routing
• Test Equipment
• PBX, PABX
• Telecommunication Systems
• Battery-Powered Systems
