SGM4727
GENERAL DESCRIPTION
The SGM4727 is a dual, bidirectional, single-pole/doublethrow (SPDT) CMOS analog switches designed to operate from a single +1.8V to +5.5V supply. It features high-bandwidth (500MHz) and low ON-resistance (9 typ), Targeted applications for audio switching.
9, 500MHz Bandwidth, Dual, SPDT Analog Switch
FEATURES
- - - - Voltage Operation : 1. 8 V to 5. 5 V On-Resistance: 9 (typ) at 5.0V High Bandwidth: 500 MHz Fast Switching Time tON 26 ns tOFF 20 ns High Off-Isolation: 66dB at 10MHz Low Crosstalk: 105dB at 10MHz Rail-to-Rail Operation TTL/CMOS Compatible Break-Before-Make Switching Extended Industrial Temperature Range: -40C to 85C Chip-Scale Package
SGM4727 features guaranteed on-resistance matching (0.3 TYP) between switches and guaranteed on-resistance flatness over the signal range (2.5 TYP). This ensures excellent linearity and low distortion when switching audio signals. The SGM4727 is a committed dual single-pole/double -throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer. SGM4727 is available in a CSP-10 package.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. (1) Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
