They are designed on an enhanced LC2MOS process that provides low power dissipation yet gives high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments. The ADG441, ADG442, and ADG444 contain four independent SPST switches. Each switch of the ADG441 and ADG444 turns on when a logic low is applied to the appropriate control input. The ADG442 switches are turned on with logic high on the appropriate control input. The ADG441 and ADG444 switches S1 IN1 S1 IN1 D1 S2 IN2 D1 S2 IN2 ADG441 ADG444 D2 S3 IN3 ADG442 D2 S3 IN3 D3 S4 IN4 D3 S4 IN4 D4 SWITCHES SHOWN FOR A LOGIC 1 INPUT D4 05233-001 FEATURES Figure 1. differ in that the ADG444 requires a 5 V logic power supply that is applied to the VL pin. The ADG441 and ADG442 do not have a VL pin, the logic power supply is generated internally by an on-chip voltage generator. Each switch conducts equally well in both directions when ON and has an input signal range that extends to the power supplies. In the OFF condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is the low charge injection for minimum transients when switching the digital inputs. PRODUCT HIGHLIGHTS 1. Extended signal range. The ADG441A/ADG442A/ ADG444A are fabricated on an enhanced LC2MOS, trenchisolated process, giving an increased signal range that extends to the supply rails. 2. Low power dissipation. 3. Low RON. 4. Trench isolation guards against latch-up for A grade parts. A dielectric trench separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions. 5. Break-before-make switching. This prevents channel shorting when the switches are configured as a multiplexer. 6. Single-supply operation. For applications where the analog signal is unipolar, the ADG441/ADG442/ADG444 can be operated from a single-rail power supply. The parts are fully specified with a single 12 V power supply. Rev.

A | Page 11 of 16 ADG441/ADG442/ADG444 TRENCH ISOLATION NMOS PMOS P-WELL N-WELL LOCO In junction isolation, the N and P wells of the PMOS and NMOS transistors form a diode that is reverse-biased under normal operation. However, during overvoltage conditions, this diode becomes forward-biased. A silicon-controlled rectifier (SCR) type circuit is formed by the two transistors causing a significant amplification of the current which, in turn, leads to latch-up. With trench isolation, this diode is removed, and the result is a latch-up proof switch. TRENCH BURIED OXIDE LAYER SUBSTRATE (BACK GATE) Figure 21. Trench Isolation Rev. A | Page 12 of 16 05233-004 In the ADG441A, ADG442A, and ADG444A, an insulating oxide layer (trench) is placed between the NMOS and the PMOS transistors of each CMOS switch. Parasitic junctions, which occur between the transistors in junction isolated switches, are eliminated, and the result is a completely latch-up proof switch.
