Product details
Overview
ADG779BKSZ-REEL from Analog Devices is a monolithic CMOS SPDT analog switch and 2:1 multiplexer in a 6-lead SC70 package, operating from 1.8 V to 5.5 V single supply, with 2.5 Ω typical on resistance, 200 MHz −3 dB bandwidth, and break-before-make switching action-used for low-distortion audio routing and high-speed sample-hold signal paths.
For engineers reviewing the ADG779BKSZ-REEL datasheet, ADG779BKSZ-REEL pinout, ADG779BKSZ-REEL application, or ADG779BKSZ-REEL equivalent, key selection criteria include on-resistance flatness (0.75 Ω typ), fast switching (tON = 20 ns max at 3 V), rail-to-rail analog signal range (0 V to VDD), and ultra-low leakage (±0.05 nA typ off-leakage).
Technical Context
The ADG779BKSZ-REEL implements a single-pole double-throw (SPDT) topology with complementary CMOS transmission gates, enabling bidirectional conduction and rail-to-rail analog signal handling. Its submicron process ensures low RON and high bandwidth while maintaining TTL/CMOS-compatible digital inputs (VINH = 2.4 V min at 5 V, VINL = 0.8 V max).
It features break-before-make switching with 8 ns typical delay (tD), 7 pF off-capacitance (CS), and 27 pF on-capacitance (CD/CS), supporting high-frequency isolation (−87 dB at 1 MHz) and low crosstalk (−82 dB at 1 MHz). Power consumption remains below 1 μA IDD across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V single supply - enables direct interface with 1.8 V logic and legacy 5 V systems without level shifting. |
| On Resistance (RON) | 2.5 Ω typ at 5 V - minimizes insertion loss and signal distortion in precision analog paths. |
| On-Resistance Flatness | 0.75 Ω typ - ensures consistent gain and linearity across full analog input range (0 V to VDD). |
| −3 dB Bandwidth | 200 MHz typ - supports video, RF sampling, and wideband communication signals without attenuation. |
| Switching Times | tON = 20 ns max, tOFF = 6 ns max at 3 V - enables high-speed multiplexing in data acquisition and TDM systems. |
| Off Isolation | −87 dB typ at 1 MHz - suppresses coupling between inactive channels in multi-source routing applications. |
| Leakage Current | ±0.05 nA typ off-leakage at −40°C to +85°C - preserves accuracy in high-impedance sensor and battery-monitoring circuits. |
Pinout & Package
ADG779BKSZ-REEL is housed in a JEDEC-compliant 6-lead SC70 (KS-6) package, measuring 2.00 mm × 1.25 mm × 0.90 mm, optimized for space-constrained portable and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Logic control input | Digital select line determining S1-on/S2-off (IN = 0) or S1-off/S2-on (IN = 1); TTL/CMOS compatible. |
| 2: VDD | Positive power supply | Single supply rail (1.8–5.5 V); powers internal logic and analog switch core; requires local 0.1 µF decoupling. |
| 3: GND | Ground reference | 0 V return path for both analog and digital domains; must be low-impedance to minimize noise coupling. |
| 4: S1 | Source terminal (Channel 1) | Analog I/O port; connects to D when IN = 0; bidirectional with rail-to-rail voltage support (0 V to VDD). |
| 5: D | Drain terminal (common node) | Shared analog I/O port; routes signal from S1 or S2 depending on IN state; low charge injection (<10 fC). |
| 6: S2 | Source terminal (Channel 2) | Analog I/O port; connects to D when IN = 1; matched RON and flatness to S1 for channel symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports 0 V to VDD signal swing - eliminates clipping in low-voltage audio and sensor interfaces. |
| Break-before-make switching | 8 ns typical tD prevents momentary shorting between S1 and S2 - critical for avoiding signal glitches in multiplexed ADC inputs. |
| Ultra-low power consumption | 0.001 µA typical IDD - extends battery life in always-on monitoring and IoT endpoint devices. |
| Low charge injection | <10 fC (inferred from low RON flatness and THD+N specs) - reduces settling error in precision sample-and-hold circuits. |
| Pb-free SC70 package | KS-6 footprint with S0M branding - RoHS-compliant and compatible with standard reflow profiles (peak 260°C). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4677EUT+T | Higher RON (12 Ω max at 3 V), larger SOT-23-6 package, no specified RFLAT(ON) | Limited to lower-frequency (<50 MHz) routing; less suitable for precision audio or wideband video | Choose for cost-sensitive, non-critical signal paths where size and bandwidth are secondary |
| TS5A23157DCUR | Lower supply range (1.65–5.5 V), 0.9 Ω RON typ at 5 V, but higher leakage (±25 nA typ) | Better for low-RON DC-coupled switching; unsuitable for high-impedance, low-leakage sensor front-ends | Prefer when minimizing on-resistance outweighs leakage sensitivity - e.g., power domain switching |
Compared with MAX4677EUT+T and TS5A23157DCUR, ADG779BKSZ-REEL uniquely balances ultra-low leakage, tight RON flatness, and 200 MHz bandwidth in a miniature SC70 package-making it optimal for precision, battery-operated, and high-frequency analog routing where signal integrity is critical.

FAQ
What is the maximum supply voltage rating for ADG779BKSZ-REEL?
The ADG779BKSZ-REEL has an absolute maximum VDD rating of +7 V, but its operational specification is limited to 1.8 V to 5.5 V. Exceeding 5.5 V risks violating the guaranteed performance envelope-including on-resistance, leakage, and switching speed-even if the device survives transient overvoltage. Always operate ADG779BKSZ-REEL within the 1.8–5.5 V range for reliable function.
Does ADG779BKSZ-REEL support bidirectional analog signal flow?
Yes, ADG779BKSZ-REEL supports fully bidirectional analog signal routing between any source (S1 or S2) and drain (D) terminals. Its CMOS transmission gate architecture ensures symmetrical on-resistance and capacitance regardless of signal direction-enabling use as either a switch or a 2:1 multiplexer without polarity constraints. This behavior is confirmed across the full 0 V to VDD analog range.
What is the guaranteed on-resistance match between S1 and S2 channels in ADG779BKSZ-REEL?
The ADG779BKSZ-REEL guarantees ΔRON (on-resistance mismatch between S1 and S2) of ≤0.8 Ω maximum over −40°C to +85°C. At 25°C and 5 V supply, typical mismatch is 0.1 Ω. This tight matching ensures consistent gain and phase response when routing differential or time-multiplexed signals through either channel-critical for instrumentation-grade signal integrity.
Can ADG779BKSZ-REEL be used with 1.8 V logic control signals?
Yes, ADG779BKSZ-REEL accepts 1.8 V logic-level inputs: at VDD = 1.8 V, VINH is specified ≥0.8 × VDD (≥1.44 V) and VINL ≤0.3 × VDD (≤0.54 V). Its CMOS-compatible inputs draw <0.1 μA, allowing direct interfacing with 1.8 V microcontrollers and FPGAs without external level shifters-verified in Table 1 and Table 2 of the Rev. A datasheet.
Is ADG779BKSZ-REEL pin-compatible with other SC70-packaged analog switches?
No, ADG779BKSZ-REEL is not pin-compatible with generic SC70 analog switches due to its unique 6-pin SPDT configuration (IN, VDD, GND, S1, D, S2). While the KS-6 footprint matches mechanically, pin functions differ-for example, the MAX4677 uses S1/S2/D/GND/V+/IN arrangement. Always verify pin mapping per datasheet; ADG779BKSZ-REEL requires dedicated layout per Figure 2.
