Product details
Overview
MAX322CUA-TG069 from Maxim Integrated is a precision dual-supply SPST analog switch featuring one normally open (NO) and one normally closed (NC) channel, ±3V to ±8V operation, 35Ω max on-resistance, guaranteed break-before-make timing (2–5ns), and 5pC max charge injection - optimized for ±5V DAC/ADC interfacing and battery-powered sample-and-hold circuits.
For engineers reviewing the MAX322CUA-TG069 datasheet, MAX322CUA-TG069 pinout, MAX322CUA-TG069 application, or MAX322CUA-TG069 equivalent, key selection criteria include bipolar supply compatibility, sub-100ns switching speed, <2.5nA leakage at +85°C, and verified break-before-make behavior critical for signal integrity in multiplexed data acquisition systems.
Technical Context
The MAX322CUA-TG069 implements complementary MOSFET pairs per switch with matched threshold design to achieve <2Ω RON matching and <4Ω RON flatness across ±3V to ±8V supplies. Its logic interface accepts VINH = V+ − 1.5V and VINL = V+ − 2.5V thresholds, enabling direct TTL/CMOS drive without level shifting.
Break-before-make timing is architecturally enforced via internal delay circuitry (tD = 2–5ns typ), preventing momentary shorting between NO and NC paths during state transitions - a deterministic feature unique to the MAX322 variant within the family and confirmed for this µMAX-packaged part.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±3V to ±8V dual supply - supports rail-to-rail analog signal switching from V− to V+ without distortion |
| On-Resistance (RON) | 35Ω max at ±5V - ensures minimal gain error and settling time impact in precision signal paths |
| RON Matching | <2Ω max between channels - enables accurate differential or ratiometric measurements |
| Charge Injection | 5pC max - limits voltage glitch on high-impedance nodes (e.g., sample capacitors in SAR ADCs) |
| Switching Speed | tON <150ns, tOFF <100ns - supports >5MHz multiplexing in real-time control loops |
| Leakage Current | <2.5nA at +85°C - preserves accuracy in low-current sensor front-ends and battery-monitoring circuits |
| Break-Before-Make Delay | 2–5ns - eliminates signal coupling between NO and NC paths during channel switching |
Pinout & Package
MAX322CUA-TG069 is housed in an 8-pin µMAX package (3mm × 3mm, 0.5mm pitch), RoHS-compliant with lead-free finish, rated for 0°C to +70°C operation and qualified for space-constrained portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply rail | Bias reference for internal logic and switch driver - must be applied before V− and signals per sequencing guidelines |
| IN1 | Logic input for Switch 1 | Controls NO1/NC1 state; logic-high connects COM1 to NO1, logic-low connects COM1 to NC1 |
| COM2 | Analog common terminal (Channel 2) | Bidirectional signal path shared between NO2 and NC2 - may serve as input or output |
| NO2 | Normally open terminal (Channel 2) | Open-circuit when IN2 = low; connects to COM2 only when IN2 = high - used for default-off signal routing |
| V− | Negative supply rail | Ground reference for negative swing; clamps inputs exceeding V− −0.3V via internal diodes |
| IN2 | Logic input for Switch 2 | Independent control of Channel 2; enables asynchronous switching of two signal paths |
| COM1 | Analog common terminal (Channel 1) | Primary signal node for Channel 1 - interfaces directly with external circuitry requiring NO/NC selection |
| NO1 | Normally open terminal (Channel 1) | Active path for Channel 1 when IN1 = high; complements NC1 to implement break-before-make function |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | 2–5ns minimum delay prevents simultaneous conduction between NO1 and NC1 - essential for avoiding signal shorting in analog muxes |
| Bipolar supply operation | Operates from ±3V to ±8V - enables direct interfacing with ±5V op-amps, DACs, and ADCs without level-shifting circuitry |
| Low charge injection (5pC max) | Minimizes voltage step on sampling capacitors - critical for maintaining 16-bit+ accuracy in switched-capacitor circuits |
| High ESD robustness | 2000V HBM per Method 3015.7 - protects against handling damage in bench and production environments |
| Low power consumption | 1.25mW typical at ±5V - extends battery life in portable test equipment and handheld medical devices |
| Temperature-stable RON | <4Ω flatness over full analog range - ensures consistent gain and linearity from −40°C to +85°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX322ESA | SO-8 package (4.9mm × 3.9mm), −40°C to +85°C temp range, same electrical specs | Better thermal performance and wider industrial temp support; larger footprint | Select when extended temperature operation or SO-8 reflow compatibility is required over space-constrained µMAX layout |
| ADG1422BRMZ | Single-supply only (5V to 36V), 1.5Ω typical RON, no break-before-make guarantee | Superior on-resistance but lacks bipolar operation and deterministic break-before-make | Choose only for unipolar systems where ultra-low RON outweighs need for ±5V compatibility and glitch-free switching |
Compared with MAX322ESA, the MAX322CUA-TG069 offers identical analog performance in a 60% smaller footprint but trades off industrial temperature range; versus ADG1422BRMZ, it provides essential bipolar operation and guaranteed break-before-make at the cost of higher RON, making it irreplaceable in ±5V mixed-signal systems demanding signal integrity.

FAQ
What is the maximum allowable supply voltage range for MAX322CUA-TG069?
The MAX322CUA-TG069 operates from ±3V to ±8V dual supplies, with absolute maximum ratings specifying V+ up to (V− − 0.3V) and +17V total differential (V+ to V−). Exceeding ±8V risks permanent damage, and operation above +70°C requires derating per the 4.10mW/°C µMAX thermal spec.
Does MAX322CUA-TG069 support rail-to-rail analog signal switching?
Yes, the MAX322CUA-TG069 supports analog signals from V− to V+ across its NO, NC, and COM terminals. Its bipolar architecture and internal clamp diodes allow full-rail operation without distortion, verified by RON flatness <4Ω over the entire ±3V to ±8V range.
Is break-before-make timing guaranteed for MAX322CUA-TG069, and what is its value?
Yes, break-before-make is a guaranteed feature specific to the MAX322 variant. For MAX322CUA-TG069, the break-before-make delay (tD) is 2–5ns, measured between turn-off of one switch and turn-on of the complementary switch - ensuring no overlap in conduction paths during state transitions.
What is the leakage current specification for MAX322CUA-TG069 at elevated temperature?
The MAX322CUA-TG069 guarantees COM on-leakage <2.5nA and NO/NC off-leakage <100pA at +85°C, validated per Method 3015.7 testing. This low leakage preserves signal integrity in high-impedance sensor interfaces and battery-monitoring circuits across the full industrial temperature range.
Can MAX322CUA-TG069 be used with single-ended 5V logic inputs?
Yes, MAX322CUA-TG069 accepts standard 5V TTL/CMOS logic levels: VINH = 3.5V (min) and VINL = 2.5V (max) when V+ = +5V. Inputs tolerate voltages down to V− without damage, and driving IN1/IN2 to V+ or V− is fully compatible with its bipolar supply architecture.
