Product details
Overview
DG407DN+ from Maxim Integrated is a dual 8-channel CMOS analog multiplexer/demultiplexer designed for precision signal routing in mixed-signal systems. It features guaranteed channel-to-channel on-resistance matching (≤8 Ω), flat on-resistance over signal range (≤9 Ω), low charge injection (≤15 pC), max 100 Ω on-resistance, and operates from ±4.5V to ±20V dual supplies or +5V to +30V single supply. It is used in data-acquisition systems requiring low distortion and rail-to-rail analog signal handling.
For engineers reviewing the DG407DN+ datasheet, DG407DN+ pinout, DG407DN+ application, or DG407DN+ equivalent, key selection criteria include guaranteed on-resistance matching across temperature, low leakage (<5 nA at +85°C), TTL/CMOS-compatible digital control, ESD protection >2000V, and PLCC-28 packaging for high-density PCB layouts.
Technical Context
The DG407DN+ implements a dual independent 8:1 analog multiplexer architecture with separate address inputs (A0–A2) and enable (EN) per section, supporting bidirectional signal flow and rail-to-rail analog voltage handling. Its CMOS switch design guarantees monotonic on-resistance behavior and minimal charge injection during channel switching.
It supports both balanced dual supplies (±4.5V to ±20V) and unbalanced or single-supply operation (+5V to +30V), with internal substrate tied to V+. Logic inputs are TTL/CMOS compatible (VAL ≤ 0.8V, VAH ≥ 2.4V), and all analog terminals tolerate voltages within (V− − 2V) to (V+ + 2V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 100 Ω - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching (max) | 8 Ω - guarantees consistent gain and offset across channels in multi-channel DAQ |
| On-Resistance Flatness (max) | 9 Ω - maintains linearity and low THD over full ±10V analog signal range |
| Charge Injection (max) | 15 pC - limits voltage glitch and settling time in sample-and-hold circuits |
| Input Off-Leakage (max) | 5 nA at +85°C - preserves accuracy in high-impedance sensor front-ends |
| ESD Protection | >2000V per MIL-STD-883 Method 3015.7 - enables robust handling in test equipment environments |
| Analog Signal Range | ±10V (dual supply) or 0V to V+ (single supply) - supports industrial sensor and audio signal levels |
Pinout & Package
DG407DN+ is housed in a 28-lead PLCC (Plastic Leaded Chip Carrier) package with gull-wing leads, RoHS-compliant and lead-free. The package provides mechanical stability and thermal performance suitable for industrial temperature operation (−40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 3–11 | S1B–S8B | Bidirectional analog inputs for second 8-channel mux section (S1B = pin 3, S8B = pin 11) |
| 12 | GND | Ground reference for logic and substrate; internally connected to V+ substrate tie |
| 13–14 | N.C. | No internal connection - must be left floating or grounded per layout best practice |
| 15–17 | A2, A1, A0 | Binary address inputs selecting one of eight channels in section B (active low EN required) |
| 18 | EN | Active-low enable for section B; high disables all S1B–S8B switches |
| 19–26 | S1A–S8A | Bidirectional analog inputs for first 8-channel mux section (S1A = pin 19, S8A = pin 26) |
| 27 | V− | Negative supply input for dual-supply operation; connect to GND for single-supply mode |
| 28 | DA | Bidirectional analog output for first 8-channel section |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG407BRZ | Single-supply only (+3V to +30V); no dual-supply support; 120 Ω max RDS(ON); 20 pC max charge injection | Lacks ±15V operation and guaranteed matching spec - unsuitable for precision bipolar DAQ | Select when cost-sensitive, single-rail systems dominate and matching specs are secondary |
| MAX4617ESE+ | Dual SPST configuration (not 8:1); 60 Ω max RDS(ON); 5 pC max charge injection; SO-16 package | Not functionally equivalent - requires redesign for channel count and topology | Choose only for low-channel-count, ultra-low-charge-injection applications where mux architecture flexibility is acceptable |
Compared with ADG407BRZ and MAX4617ESE+, the DG407DN+ uniquely delivers guaranteed 8 Ω channel matching, dual-supply operation, and PLCC-28 packaging - making it the only option qualified for high-reliability, multi-channel industrial DAQ where signal path consistency and temperature stability are mandatory.

FAQ
What is the operating temperature range for DG407DN+?
The DG407DN+ is rated for operation from −40°C to +85°C. This extended industrial temperature range is validated across all key parameters including on-resistance matching (≤8 Ω), leakage current (<5 nA at +85°C), and switching performance. The PLCC-28 package contributes to thermal stability in convection-cooled enclosures typical of test and control equipment.
Does DG407DN+ support single-supply operation?
Yes, DG407DN+ supports +5V to +30V single-supply operation. In this mode, V− must be connected to GND. The analog signal range extends from 0V to V+, and all logic inputs remain TTL/CMOS compatible. Performance specifications-including 100 Ω max on-resistance and 15 pC max charge injection-are guaranteed across the full single-supply range and temperature span.
Is DG407DN+ pin-compatible with older DG407 variants?
Yes, DG407DN+ is a pin-compatible plug-in upgrade for industry-standard DG407 devices. It retains identical PLCC-28 pinout, address/control logic, and supply connections. Key improvements-including guaranteed 8 Ω channel matching and tighter charge injection-require no PCB or firmware changes, enabling immediate performance enhancement in existing designs.
What is the maximum analog signal voltage DG407DN+ can handle?
DG407DN+ supports analog signals from V− to V+ under normal operation. With ±15V dual supplies, the full range is ±15V; with +12V single supply (V− = GND), the range is 0V to +12V. Absolute maximum ratings allow transient excursions to (V− − 2V) and (V+ + 2V), but sustained operation beyond V− to V+ may increase leakage or distortion.
How does DG407DN+ achieve low charge injection?
DG407DN+ achieves ≤15 pC max charge injection through matched transistor geometry, optimized gate drive timing, and internal charge cancellation circuitry. This specification is 100% tested at +85°C and guaranteed by correlation at +25°C. In practice, it enables sub-LSB settling in 16-bit sample-and-hold circuits using standard 1 nF hold capacitors without additional blanking or correction.
