1 LC 2 MOS Precision Analog Switch in MSOP AG49-EP FEATURES 44 V supply maximum ratings VSS to V analog signal range Low on resistance: <35 Ω Ultralow power dissipation: <35 μw Fast transition time: 45 ns maximum Break-before-make switching action Plug-in replacement for G49 Supports defense and aerospace applications (AQEC standard) Military temperature range: 55 C to +25 C Controlled manufacturing baseline One assembly/test site One fabrication site Enhanced product change notification Qualification data available on request APPLICATIONS Precision test equipment Precision instrumentation Battery-powered systems Sample-and-hold systems GENERAL ESCRIPTION The AG49-EP is a monolithic CMOS SPT switch. This switch is fabricated on an enhanced LC 2 MOS process that provides low power dissipation yet gives high switching speed, low on resistance, and low leakage current. The on resistance profile of the AG49-EP is very flat over the full analog input range, ensuring excellent linearity and low distortion. The part also exhibits high switching speed and high signal bandwidth. CMOS construction ensures ultralow power dissipation, making the part ideally suited for portable and battery-powered instruments. Each switch of the AG49-EP conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The AG49-EP exhibits break-before-make switching action. Full details about this enhanced product are available in the AG49 data sheet, which should be consulted in conjunction with this data sheet.

The AG49-EP is fabricated on an enhanced LC 2 MOS process, giving an increased signal range that extends to the supply rails. 2. Ultralow Power issipation. 3. Low RON. 4. Single-Supply Operation. For applications where the analog signal is unipolar, the AG49-EP can be operated from a single rail power supply. The part is fully specified with a single 2 V power supply and remains functional with single supplies as low as 5 V.
