Product details
Overview
DG507BEQ-T1-GE3 from Vishay Siliconix is a dual 8-channel differential CMOS analog multiplexer designed for high-precision signal routing in data acquisition and instrumentation systems. It supports ±15 V dual supply or +12 V single supply operation, delivers 217 MHz -3 dB bandwidth, exhibits ultra-low 1 pC charge injection, and maintains <3 pA leakage at 125 °C - enabling accurate switching in battery-powered avionics and medical devices.
For engineers reviewing the DG507BEQ-T1-GE3 datasheet, DG507BEQ-T1-GE3 pinout, DG507BEQ-T1-GE3 application, or DG507BEQ-T1-GE3 equivalent, key selection criteria include its break-before-make switching, differential channel architecture, TSSOP28 package compatibility, and guaranteed performance across -40 °C to +125 °C.
Technical Context
The DG507BEQ-T1-GE3 implements a 3-bit binary address decoder driving eight independent differential switch pairs (S1a/S1b through S8a/S8b), each with matched on-resistance (ΔRDS(on) ≤ 10 Ω) and symmetrical conduction. Its enhanced SG-II CMOS process minimizes parasitic capacitance (CD(on) = 24 pF, CS(off) = 4 pF) and enables rail-to-rail analog signal handling from V− to V+.
Break-before-make timing (tOPEN ≤ 10 ns at full temperature range) prevents transient crosstalk between adjacent differential channels. The EN input resets all switches to off-state, supporting cascaded configurations without signal contention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Channels | Dual 8-channel differential - routes one of eight differential inputs to common Da/Db outputs. |
| Supply Range | ±5 V to ±20 V dual or +12 V single - supports wide industrial and avionics voltage rails. |
| Bandwidth | 217 MHz (-3 dB) - preserves signal integrity up to high-frequency sensor and audio signals. |
| Charge Injection | 1 pC (full temp range) - minimizes voltage glitch on sampled-hold nodes in precision ADC front-ends. |
| Leakage Current | <3 pA at 125 °C - ensures low offset drift in high-impedance medical electrode interfaces. |
| On-Resistance | 300 Ω max (dual ±15 V), 450 Ω max (single +12 V) - maintains linearity in 12-bit+ data acquisition paths. |
| Off Isolation | -84 dB at 1 MHz - suppresses coupling between active and inactive differential sensor channels. |
Pinout & Package
The DG507BEQ-T1-GE3 is housed in a 28-pin TSSOP package (JEDEC MO-153, 9.7 mm × 4.4 mm × 1.0 mm), lead-free and RoHS-compliant, with exposed pad for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive power supply | Accepts up to +44 V; defines upper analog rail for differential channel conduction. |
| V- | Negative power supply | Accepts down to -44 V; defines lower analog rail; enables true bipolar signal switching. |
| GND | Analog/digital reference | Common return for logic inputs and internal biasing; must be low-impedance for THD < 0.23 %. |
| A0–A2 | Binary address inputs | 3-bit code selects one of eight differential pairs (S1a/S1b to S8a/S8b); TTL-compatible. |
| EN | Enable control | Active-high; forces all switches open when low - essential for stacking multiple DG507B devices. |
| S1a–S8a | Differential input A terminals | Eight analog inputs tied to Da output when selected; matched layout minimizes skew. |
| S1b–S8b | Differential input B terminals | Corresponding complement inputs tied to Db output; maintains common-mode rejection. |
| Da, Db | Differential outputs | Common output pair; supports fully differential signal path to ADC driver or instrumentation amp. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply flexibility | Operates from ±5 V to ±20 V or +12 V single supply - eliminates need for external level shifters in mixed-rail systems. |
| Rail-to-rail analog swing | VANALOG = V− to V+ - preserves full dynamic range of sensors and transducers without clipping. |
| Break-before-make switching | tOPEN ≤ 10 ns over -40 °C to +125 °C - prevents momentary shorting between differential channel pairs during address transitions. |
| Ultra-low leakage | IS(off), ID(off) ≤ ±50 pA at 125 °C - critical for high-impedance pH, ECG, and piezoelectric sensor interfaces. |
| Low THD | 0.23 % at 5 Vrms, 20 Hz–20 kHz - meets audio-grade routing requirements in test equipment and broadcast gear. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual differential analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG507A | Higher on-resistance (400 Ω max), wider RDS(on) matching (25 Ω), no guaranteed 125 °C operation. | Limited to commercial/industrial temp range (-40 °C to +85 °C); unsuitable for extended-temperature avionics or under-hood test gear. | Select DG507BEQ-T1-GE3 when full -40 °C to +125 °C operation, tighter matching, or lower leakage is required. |
| DG507A | Same pinout but higher charge injection (3 pC vs. 1 pC), higher THD (0.35 %), and no 125 °C characterization. | Not qualified for high-reliability medical or aerospace use where long-term parameter stability is mandated. | Choose DG507BEQ-T1-GE3 for designs requiring documented 125 °C performance, lower glitch energy, or compliance with IEC 60601-1 leakage limits. |
Compared with ADG507A and DG507A, the DG507BEQ-T1-GE3 provides superior temperature range coverage, lower charge injection for precision sampling, and tighter on-resistance matching - directly improving measurement repeatability in high-end test and medical systems.

FAQ
What is the maximum supply voltage rating for the DG507BEQ-T1-GE3?
The DG507BEQ-T1-GE3 has an absolute maximum V+ to V− rating of 44 V, with individual supply pins rated to +44 V referenced to V− and -44 V referenced to V+. This allows safe operation with ±20 V supplies or +40 V single-ended configurations, provided total differential voltage remains within limit.
Does the DG507BEQ-T1-GE3 support single-supply operation?
Yes, the DG507BEQ-T1-GE3 supports single-supply operation at +12 V (V+ = 12 V, V− = 0 V), maintaining full functionality including TTL-compatible logic inputs, break-before-make switching, and analog signal range from 0 V to 12 V - verified per datasheet Section "SPECIFICATIONS Single Supply 12 V".
What is the guaranteed operating temperature range for DG507BEQ-T1-GE3?
The DG507BEQ-T1-GE3 is specified and tested over -40 °C to +125 °C (A suffix), with all key parameters - including leakage current, on-resistance, charge injection, and switching times - guaranteed across this full industrial/automotive range per datasheet Rev. C.
How does the break-before-make interval behave across temperature?
The DG507BEQ-T1-GE3 guarantees tOPEN ≤ 10 ns over the full -40 °C to +125 °C range, as confirmed in the "Dynamic Characteristics" table. This ensures consistent channel isolation during address changes regardless of ambient or junction temperature in harsh environments.
Is the DG507BEQ-T1-GE3 pin-compatible with earlier DG507A versions?
Yes, the DG507BEQ-T1-GE3 uses identical pinout and footprint as DG507A in TSSOP28, enabling drop-in replacement. However, it improves charge injection (1 pC vs. 3 pC), THD (0.23 % vs. 0.35 %), and extends guaranteed operation to +125 °C - making DG507BEQ-T1-GE3 a direct functional upgrade.
