Product details
Overview
DG408CUE+T from Maxim Integrated is a precision 1-of-8 CMOS analog multiplexer/demultiplexer designed for bidirectional signal routing in data-acquisition and test systems. It delivers guaranteed on-resistance ≤100Ω, channel-to-channel matching ≤8Ω, and low charge injection ≤15pC, operating from +5V to +30V single supply or ±5V to ±20V dual supplies. Its rail-to-rail analog signal handling and TTL/CMOS-compatible digital inputs make it suitable for high-fidelity analog switching in industrial instrumentation.
For engineers reviewing the DG408CUE+T datasheet, DG408CUE+T pinout, DG408CUE+T application, or DG408CUE+T equivalent, this page provides verified specifications, TSSOP-16 package details, functional pin mapping, real-world use cases in sample-and-hold and audio routing, and two validated alternative parts with documented technical differences.
Technical Context
The DG408CUE+T implements an 8-channel analog switch matrix controlled by three address bits (A0–A2) and an active-low enable (EN), with internal CMOS decoding logic selecting exactly one of eight bidirectional Sx-to-D paths. All channels exhibit matched on-resistance across temperature and signal voltage, enabling precise gain/offset calibration in multichannel sensor interfaces.
Its architecture supports both single-supply (V− = GND) and split-supply operation, with ESD protection >2000V per MIL-STD-883 Method 3015.7 and guaranteed leakage <5nA at +85°C - critical for low-drift, high-impedance front-end designs where off-channel crosstalk and charge injection must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (rDS(ON)) | ≤100Ω max at +25°C; ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching | ≤8Ω max between any two channels; enables accurate channel-to-channel ratio matching in differential or ratiometric systems |
| Charge Injection | ≤15pC max; limits voltage glitch on hold capacitors in sample-and-hold circuits to <1.5mV with 10nF capacitor |
| Analog Signal Range | ±10V with ±15V supplies; supports full rail-to-rail input/output swing without clipping |
| Supply Voltage Range | +5V to +30V single or ±5V to ±20V dual; allows flexible integration into legacy and modern power domains |

Applications
| Sample-and-Hold Circuits | Test Equipment |
|---|---|
Use Scenario: Multiplexing multiple sensor outputs into a single ADC input while maintaining precise hold capacitor voltage integrity. IC Role / Device Role / Timing Role: Analog switch controlling connection between sensor array and hold capacitor; low charge injection prevents voltage step errors during channel change. Use Value: ≤15pC charge injection limits hold-step error to <1.5mV with 10nF capacitor, enabling 12-bit+ effective resolution. |
Use Scenario: Automated signal routing in benchtop multimeters and automated test equipment (ATE) for stimulus/response path selection. IC Role / Device Role / Timing Role: High-fidelity analog path selector with low crosstalk (<−92dB) and fast enable timing (150ns). Use Value: −92dB crosstalk isolates measurement channels from stimulus sources, preventing false readings during parallel testing. |
| Guidance and Control Systems | Audio Signal Routing |
Use Scenario: Selecting among redundant inertial measurement unit (IMU) outputs in flight control computers requiring fault-tolerant analog voting. IC Role / Device Role / Timing Role: Precision analog multiplexer providing matched gain paths for sensor fusion algorithms. Use Value: ≤8Ω on-resistance matching ensures <0.1% gain mismatch between channels, critical for voting consistency. |
Use Scenario: Channel selection in professional audio mixers and effects processors handling line-level analog signals. IC Role / Device Role / Timing Role: Bidirectional analog switch routing stereo pairs with minimal THD and no audible pop/click. Use Value: Rail-to-rail ±10V capability supports pro-audio signal levels; 100Ω on-resistance avoids level loss in 10kΩ line drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | On-resistance 120Ω max (vs. 100Ω), charge injection 25pC max (vs. 15pC), operates up to +36V single supply | Higher on-resistance increases gain error in precision gain stages; higher charge injection degrades sample-and-hold accuracy | Select ADG408BRUZ only if extended supply voltage (>30V) is required and 12-bit resolution suffices |
| MAX4617ESE+ | Single 8-channel mux with 45Ω on-resistance but limited to +5.5V supply; no dual-supply support | Cannot replace DG408CUE+T in ±15V or +24V systems; unsuitable for rail-to-rail industrial signal ranges | Choose MAX4617ESE+ only for low-voltage, low-on-resistance applications where supply headroom is constrained to 5V |
Compared with ADG408BRUZ and MAX4617ESE+, the DG408CUE+T uniquely balances low on-resistance (≤100Ω), ultra-low charge injection (≤15pC), and wide supply flexibility (±5V to ±20V / +5V to +30V), making it optimal for high-accuracy, mixed-supply industrial data acquisition where channel matching and signal fidelity are non-negotiable.

FAQ
What is the maximum supply voltage rating for DG408CUE+T?
The DG408CUE+T supports a single supply up to +30V (V+ to GND) or dual supplies up to ±20V (V+ to V−). Absolute maximum ratings specify V+ to V− ≤ 44V and V+ to GND ≤ 25V. Exceeding these may cause permanent damage. Operation at ±15V is typical for optimal on-resistance and leakage performance.
Does DG408CUE+T support rail-to-rail analog signal switching?
Yes, DG408CUE+T supports rail-to-rail analog signal handling - signals can swing from V− to V+ without clipping or distortion. With ±15V supplies, this enables ±10V analog range; with +12V single supply (V− = GND), the range is 0V to +10V. This is confirmed in the Electrical Characteristics table under VANALOG parameter.
What is the guaranteed on-resistance matching specification for DG408CUE+T?
The DG408CUE+T guarantees on-resistance matching of ≤8Ω maximum between any two channels across temperature and signal voltage. This is measured as ΔrDS(ON) = rDS(ON)(max) − rDS(ON)(min) and is specified in the Electrical Characteristics table for both dual- and single-supply conditions.
Is DG408CUE+T pin-compatible with the original DG408?
Yes, DG408CUE+T is explicitly designed as a pin-compatible plug-in upgrade for the industry-standard DG408. The pin configuration, function mapping, and timing behavior are identical - no PCB layout changes are required when replacing legacy DG408 variants with DG408CUE+T in existing designs.
What is the maximum charge injection value for DG408CUE+T, and why does it matter?
The DG408CUE+T guarantees maximum charge injection of 15pC. This matters because injected charge causes voltage glitches on hold capacitors in sample-and-hold circuits; with a 10nF capacitor, 15pC yields only 1.5mV error - enabling accurate 12-bit+ data acquisition without additional correction circuitry.
