Product details
Overview
DG212BDJ-E3 from Vishay Siliconix is a quad SPST normally open analog switch IC designed for precision signal routing in ±15 V dual-supply systems. It features 50 Ω typical on-resistance, 20 pA max off-leakage, 120 ns typical turn-on time, 1 pC charge injection, and supports ±22 V analog signal range - enabling high-fidelity switching in sample-and-hold circuits and programmable gain amplifiers.
For engineers reviewing the DG212BDJ-E3 datasheet, DG212BDJ-E3 pinout, DG212BDJ-E3 application, or DG212BDJ-E3 equivalent, this device is selected for low-distortion analog multiplexing where bi-directional signal integrity, minimal transient injection, and rail-to-rail analog handling are critical in industrial instrumentation and test equipment designs.
Technical Context
The DG212BDJ-E3 implements four independent CMOS transmission gates with true bi-directional conduction when enabled and full blocking to supply rails when disabled. Its silicon-gate process delivers matched rDS(on) ≤2 Ω between channels and latch-up immunity via epitaxial isolation.
It operates with TTL/CMOS-compatible logic inputs (VINH ≥2.4 V, VINL ≤0.8 V), supports single-supply (V+ = +12 V, V− = GND) or dual-supply (±15 V) configurations, and maintains stable on-resistance across −40 °C to +85 °C with <100 ppm/°C drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail input/output swing without clipping in dual-supply systems |
| rDS(on) Typ. | 50 Ω - ensures minimal insertion loss and voltage drop in precision signal paths |
| tON / tOFF | 120 ns / 100 ns - enables fast channel switching in data acquisition and filter selection |
| Charge Injection | 1 pC - limits hold-mode error in sample-and-hold applications to sub-mV levels |
| ID(off) Max | ±0.02 nA at ±14 V - preserves DC accuracy in high-impedance sensor interfaces |
| Supply Voltage Range | ±4.5 V to ±22 V - accommodates wide dynamic range in industrial and telecom front-ends |
| Logic Compatibility | TTL/CMOS - simplifies interface with microcontrollers and FPGA I/O without level shifters |

Applications
| Sample-and-Hold Circuits | Programmable Gain Amplifiers |
|---|---|
|
Use Scenario: Capturing and holding analog sensor outputs for ADC conversion in data loggers. IC Role / Device Role / Timing Role: Precision analog switch controlling acquisition window timing and isolating hold capacitor from source impedance.

Use Scenario: Digitally selecting feedback resistor networks to set amplifier gain in automated test equipment. IC Role / Device Role / Timing Role: Low-leakage, low-rDS(on) switch routing between discrete gain-setting resistors. Use Value: ±0.02 nA off-leakage prevents gain drift; 50 Ω rDS(on) introduces <0.05% gain error in 100 kΩ feedback paths. |
| Automated Test Equipment (ATE) | Industrial Process Monitoring |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4618ESE+ | Single-supply only (+2.7 V to +12 V); 60 Ω rDS(on); 0.5 pC charge injection | Limited to unipolar systems; lower leakage (0.1 pA) but no negative rail support | Select when operating exclusively from +5 V or +12 V supplies and ultra-low charge injection is prioritized over bipolar range |
| ADG1412BRUZ | 4-channel, SPST, ±15 V rated; 1.8 Ω rDS(on); 0.25 pC charge injection; 16-lead TSSOP | Lower on-resistance and charge injection, but requires PCB redesign due to surface-mount TSSOP package | Select when upgrading for higher precision in space-constrained layouts and rework is acceptable |
Compared with DG212BDJ-E3, MAX4618ESE+ lacks dual-supply capability and rail-to-rail analog handling, while ADG1412BRUZ offers superior analog performance but mandates SMT assembly and layout change - making DG212BDJ-E3 optimal for through-hole, ±15 V, cost-sensitive industrial signal routing.

FAQ
What is the maximum analog signal voltage supported by DG212BDJ-E3?
The DG212BDJ-E3 supports analog signals from V− to V+, with absolute maximum ratings of ±22 V across V+ and V−. In standard ±15 V operation, it reliably passes ±15 V signals with full rail-to-rail linearity and less than 0.1% THD - verified per Figure 1 and Absolute Maximum Ratings table in Document Number 70040.
Does DG212BDJ-E3 require separate logic and analog supplies?
Yes, DG212BDJ-E3 uses dedicated VL (pin 12) for logic-level referencing and V+/V− (pins 16/4) for analog signal handling. VL accepts 5 V for TTL/CMOS compatibility, while V+/V− can be independently biased - enabling mixed-voltage system integration without level-shifting circuitry.
Can DG212BDJ-E3 operate from a single +12 V supply?
Yes, DG212BDJ-E3 supports single-supply operation with V+ = +12 V and V− = GND (pin 4 tied to GND). In this mode, the analog signal range is 0 V to +12 V, rDS(on) increases to 90–200 Ω, and charge injection rises to 4 pC - all specified in the "SPECIFICATIONS for Single Supply" section of the datasheet.
What is the thermal derating behavior of DG212BDJ-E3 above 75 °C?
DG212BDJ-E3 has a thermal derating factor of 6.5 mW/°C above 75 °C for its 16-pin plastic DIP package. At 100 °C ambient, maximum allowable power dissipation drops from 470 mW to 277.5 mW - calculated as 470 mW − (25 °C × 6.5 mW/°C) - ensuring safe operation within SOA limits under extended industrial temperature profiles.
How does DG212BDJ-E3 differ from the legacy DG212?
DG212BDJ-E3 is the enhanced B-version: it improves on-resistance (50 Ω vs. 60 Ω typ), reduces leakage (20 pA vs. 100 pA max), cuts switching time (120 ns vs. 200 ns), lowers charge injection (1 pC vs. 5 pC), and adds RoHS-compliant lead-free terminations - all confirmed in the "Improved Quad CMOS Analog Switches" product description and revision history of Document Number 70040.
