Product details
Overview
DG212BDQ-T1-E3 from Vishay Siliconix is a quad SPST normally open analog switch IC designed for precision signal routing in instrumentation and test systems. It supports ±22 V analog signal range, features 50 Ω typical on-resistance, 1 pC charge injection, 120 ns turn-on time, and operates across –40 °C to +85 °C - enabling high-fidelity sampling in sample-and-hold circuits.
For engineers reviewing the DG212BDQ-T1-E3 datasheet, DG212BDQ-T1-E3 pinout, DG212BDQ-T1-E3 application, or DG212BDQ-T1-E3 equivalent, key selection criteria include bi-directional analog switching capability, low leakage (±0.02 nA), RoHS-compliant TSSOP-16 packaging, and compatibility with ±15 V dual-supply or +12 V single-supply configurations.
Technical Context
The DG212BDQ-T1-E3 implements four independent CMOS transmission gates with true bi-directional conduction when enabled and rail-to-rail blocking in the off state. Its epitaxial layer prevents latch-up, and internal clamping diodes protect against overvoltage transients on S/D/IN pins beyond supply rails.
It uses silicon gate CMOS process technology to achieve lower rDS(on), reduced leakage, and faster switching versus legacy DG212 - with guaranteed 30 mA continuous current per channel and logic-level compatibility (VINH ≥ 2.4 V, VINL ≤ 0.8 V) at VL = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (full-range operation with ±15 V supplies); enables handling of industrial sensor outputs without level-shifting |
| rDS(on) | 45 Ω typ. (VD = ±10 V, IS = 1 mA); ensures minimal signal attenuation and distortion in precision analog paths |
| Charge Injection | 1 pC typ.; reduces voltage glitch and settling error in sample-and-hold and multiplexed ADC front-ends |
| tON/tOFF | 120 ns / 100 ns typ.; supports fast channel switching in automated test equipment scan sequences |
| ID(on) | ±0.02 nA max. at ±14 V; maintains high DC accuracy in high-impedance measurement circuits |
| Off Isolation (OIRR) | 90 dB at 100 kHz; minimizes crosstalk between adjacent channels in multi-signal acquisition systems |
| Supply Range | ±4.5 V to ±22 V dual; or +4.5 V to +25 V single; provides flexibility in legacy and modern power architectures |
Pinout & Package
Package: 16-lead TSSOP (JEDEC MO-153, MS-012), 4.4 mm × 5.0 mm body, 0.65 mm pitch, RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input | Active-high logic inputs; drive internal gate drivers; TTL/CMOS compatible with 2.4 V min high, 0.8 V max low |
| 2, 6, 10, 14 (S1–S4) | Source terminal | Bi-directional analog node; connects to signal source or load depending on system topology |
| 3, 7, 11, 15 (D1–D4) | Drain terminal | Bi-directional analog node; paired with corresponding Sx to form SPST switch path |
| 4 (V+) | Positive supply rail | Bias for P-channel MOSFETs; must be ≥ |V−| for full analog range compliance |
| 8 (V−) | Negative supply rail | Bias for N-channel MOSFETs; sets lower bound of analog signal swing |
| 12 (GND) | Logic ground reference | Reference for digital input thresholds and VL supply; isolated from analog power grounds in mixed-signal layout |
| 16 (VL) | Logic supply voltage | Defines logic threshold levels; typically 5 V; decoupling required for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Improved charge injection compensation | 1 pC typical - directly reduces aperture error and hold-step error in precision sample-and-hold designs |
| True bi-directional analog switching | Signal flows equally well from S→D or D→S when ON - eliminates need for direction-aware routing in multiplexer layouts |
| Rail-to-rail analog blocking | Blocks signals up to V+ and down to V− in OFF state - prevents leakage-induced offset in high-gain amplifier inputs |
| Latch-up immunity | Epitaxial substrate structure - allows safe operation in noisy industrial environments with transient coupling |
| Extended temperature operation | –40 °C to +85 °C - validated for use in uncontrolled ambient test racks and portable instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4618ESE+ | Higher rDS(on) (100 Ω typ.), wider supply range (±20 V), but higher charge injection (3 pC) | Less suitable for sub-10 µV precision hold circuits; better for general-purpose multiplexing | Select when cost sensitivity outweighs ultra-low charge injection requirements |
| ADG1412BRUZ | Lower rDS(on) (1.8 Ω typ.), but narrower analog range (±15 V max), higher supply current (120 µA) | Preferred for low-distortion audio routing; less optimal for wide-range industrial sensors | Select when ultra-low on-resistance is critical and supply headroom permits |
Compared with DG212BDQ-T1-E3, MAX4618ESE+ trades lower cost for higher charge injection and on-resistance, while ADG1412BRUZ delivers superior rDS(on) at the expense of higher quiescent current and reduced voltage margin - making DG212BDQ-T1-E3 the balanced choice for wide-range, low-leakage, medium-speed instrumentation.

FAQ
What is the maximum analog signal voltage supported by DG212BDQ-T1-E3?
DG212BDQ-T1-E3 supports analog signals from V− to V+, with absolute maximum ratings of ±22 V supply and ±15 V analog range under standard ±15 V operation. Signals exceeding V+ or V− are clamped by internal diodes; forward current must be limited to rated values per datasheet Note a.
Is DG212BDQ-T1-E3 pin-compatible with the original DG212?
No - DG212BDQ-T1-E3 is part of the improved DG212B series and shares identical pinout with DG212B variants (TSSOP-16), but is not pin-compatible with legacy DG212 (which used different package footprints and electrical specs). Always verify package dimensions and thermal pad layout against Vishay Document 71261.
Can DG212BDQ-T1-E3 operate from a single +12 V supply?
Yes - DG212BDQ-T1-E3 supports single-supply operation with V+ = +12 V and V− = 0 V, delivering 0 V to +12 V analog signal range. Logic supply VL remains at 5 V, and specifications such as rDS(on) (90 Ω typ.) and tON (300 ns) are characterized under this condition per datasheet Section "SPECIFICATIONS for Single Supply".
What is the thermal derating behavior of DG212BDQ-T1-E3 above 75 °C?
DG212BDQ-T1-E3 has a thermal derating factor of 7.6 mW/°C above 75 °C for TSSOP packages, as specified in Absolute Maximum Ratings. Total power dissipation must be reduced linearly beyond this point to maintain junction temperature within safe limits - e.g., at 100 °C ambient, max allowable power drops to 640 mW − (25 °C × 7.6 mW/°C) = 450 mW.
Does DG212BDQ-T1-E3 require external pull-up or pull-down resistors on its digital inputs?
No - DG212BDQ-T1-E3 digital inputs are TTL/CMOS compatible with defined thresholds (VINH ≥ 2.4 V, VINL ≤ 0.8 V) and low input current (±1 µA), so direct connection to 5 V logic outputs is sufficient. External resistors are unnecessary unless interfacing with open-drain or high-impedance sources where noise immunity is critical.
