DG401, DG403, DG405 Data Sheet June 1999 File Number 3284.6 Monolithic CMOS Analog Switches Features The DG401, DG403 and DG405 monolithic CMOS analog switches have TTL and CMOS compatible digital inputs. • ON Resistance (Max) . . . . . . . . . . . . . . . . . . . . . . . . . 45Ω These switches feature low analog ON resistance (<45Ω) and fast switch time (tON < 150ns). Low charge injection simplifies sample and hold applications. The improvements in the DG401/403/405 series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling 30VP-P signals. Power supplies may be single-ended from +5V to +34V, or split from ±5V to ±17V. • Low Power Consumption (PD) . . . . . . . . . . . . . . . . . . <35µW • Fast Switching Action - tON (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 150ns - tOFF (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100ns • Low Charge Injection • DG401 Dual SPST; Same Pinout as HI-5041 • DG403 Dual SPDT; DG190, IH5043, IH5151, HI-5051 • DG405 Dual DPST; DG184, HI-5045, IH5145 The analog switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with analog signals is quite low over a ±15V analog input range. The three different devices provide the equivalent of two SPST (DG401), two SPDT (DG403) or two DPST (DG405) relay switch contacts with CMOS or TTL level activation. The pinout is similar, permitting a standard layout to be used, choosing the switch function as needed. • TTL, CMOS Compatible Pinouts • Hi-Rel Systems DG401 (PDIP, SOIC) TOP VIEW • Single or Split Supply Operation Applications • Audio Switching • Battery Operated Systems • Data Acquisition • Sample and Hold Circuits • Communication Systems D1 1 16 S1 NC 2 15 IN1 NC 3 14 V- NC 4 13 GND NC 5 12 VL NC 6 11 V+ NC 7 10 IN2 DG401DJ -40 to 85 16 Ld PDIP E16.3 D2 8 9 S2 DG401DY -40 to 85 16 Ld SOIC M16.15 DG403DJ -40 to 85 16 Ld PDIP E16.3 DG403DY -40 to 85 16 Ld SOIC M16.15 DG405DY -40 to 85 16 Ld SOIC M16.15 DG403, DG405 (SOIC) TOP VIEW D1 1 16 S1 NC 2 15 IN1 D3 3 14 V- S3 4 13 GND S4 5 12 VL D4 6 • Automatic Test Equipment Ordering Information PART NUMBER TEMP.

CAPACITANCES TEST CIRCUIT C DG401, DG403, DG405 Application Information Dual Slope Integrators Peak Detector The DG403 is well suited to configure a selectable slope integrator. One control signal selects the timing capacitor C1 or C2 . Another one selects eIN or discharges the capacitor in preparation for the next integration cycle. A3 acting as a comparator provides the logic drive for operating SW1 . The output of A2 is fed back to A3 and compared to the analog input eIN . If eIN > eOUT the output of A3 is high keeping SW1 closed. This allows C1 to charge up to the analog input voltage. When eIN goes below eOUT, A3 goes negative, turning SW1 off. The system will therefore store the most positive analog input experienced. +5V +15V VL eIN V+ S1 D1 S3 D2 eOUT RESET IN1 INTEGRATE/ RESET TTL S2 D3 S4 D4 C1 IN2 SW2 + C2 GND R1 A2 + - eIN DG403 SCOPE SELECT SW1 A1 eOUT C1 + - V- DG401 A3 -15V FIGURE 8.
