ADA4096-4ACPZ-R7 Übersicht
A quad operational amplifier (quad op-amp) is an integrated circuit that combines four independent, internally compensated op-amp channels on one die. Quad op-amps sit within the broader op-amp family (single, dual, quad) under the linear IC category and ultimately within analog signal-chain components. They are typically used to save board area, reduce BOM count, and provide matched channel-to-channel DC offset and bandwidth behavior in multi-channel designs such as sensor arrays, instrumentation front-ends, and active filters.
Key features include overvoltage protection (OVP) on the inputs of 32 V beyond either supply rail with no phase reversal or latch-up, true rail-to-rail input and output swing, low power consumption of 60 uA per amplifier typical, and robust ESD rating suitable for industrial handling. The LFCSP-WQ-16 (3x3) package provides an exposed thermal pad that lowers thermal resistance and enables higher channel density PCB layouts.
Architecturally, the ADA4096-4 uses a CMOS input stage with internal OVP clamp diodes that protect the device when sensor signals or fault conditions drive the input beyond the supply rails. The wide operating range and OVP make it ideal for industrial environments where transients, mis-wiring, or large common-mode excursions would damage conventional op-amps. The micropower quiescent current is achieved through a class-AB output stage biased for low Iq rather than high slew rate.
Typical applications include battery monitoring and charger control in portable equipment, industrial process control signal conditioning, sensor interfaces (thermocouple, RTD, strain-gauge bridges), power-supply current-sense amplification, and analog filtering or summing networks. The OVP feature also makes the part suitable for use as a buffer at the input of data-acquisition systems that may be exposed to transients.
When designing with this part, place a 0.1 uF decoupling capacitor near each supply pin and use guard traces around high-impedance input nodes to minimize leakage. Avoid driving capacitive loads greater than 500 pF without an isolation resistor, and ensure the input common-mode voltage stays within the OVP window under all transient conditions.

Typische Anwendungen
ADA4096-4ACPZ-R7 ist geeignet für 6 Anwendungs: Battery Monitoring and Charger Control, Industrial Process Control Signal Conditioning, Sensor Interface Buffers, Active Filter and Summing Circuits, Data Acquisition Input Buffers, Power Supply Current Sensing.
Battery Monitoring and Charger Control
The ADA4096-4ACPZ-R7's 60 uA per-channel quiescent current and 3V-30V single-supply operation make it ideal for battery monitoring in portable equipment. Each of the four channels can be configured as a separate voltage follower or differential amplifier to monitor individual cell voltages in a multi-cell battery pack, with the total IC current of ~240 uA having negligible impact on overall battery drain. The 32V input OVP allows direct connection to 24V battery stacks without external protection circuitry.
Empfohlen
Industrial Process Control Signal Conditioning
In industrial process control, the ADA4096-4ACPZ-R7's overvoltage-protected inputs (32V beyond rails) and wide 3V-30V supply range make it suitable for conditioning signals from 4-20 mA loops, thermocouples, and pressure transducers in factory automation. The quad package allows four independent channels to handle multiple sensor inputs on a single IC. The OVP feature is critical in industrial environments where mis-wiring or transients on sensor lines would otherwise damage a conventional op-amp.
Empfohlen
Sensor Interface Buffers
The ADA4096-4ACPZ-R7 excels as a buffer/amplifier for sensor signals in IoT and portable devices. The rail-to-rail input and output swing allows it to handle sensor signals that swing close to either supply rail, while the 60 uA Iq preserves battery life. The OVP feature protects against electrostatic discharge and fault conditions on sensor lines. The 3x3 mm LFCSP package enables compact PCB layouts in space-constrained wearable and IoT designs.
Empfohlen
Active Filter and Summing Circuits
The ADA4096-4ACPZ-R7's rail-to-rail I/O and four channels per package make it well-suited for implementing active filters (low-pass, high-pass, band-pass) and summing/inverting amplifiers in signal conditioning paths. With four matched channels on one die, channel-to-channel gain matching is consistent, which is important for multi-pole Sallen-Key filters. The micropower operation preserves battery life in portable audio and measurement equipment.
Empfohlen
Data Acquisition Input Buffers
The ADA4096-4ACPZ-R7 serves as an ideal input buffer for multi-channel data acquisition systems where input signals may exceed the ADC supply range. Its 32V OVP allows the ADC inputs to be protected even when external sensors or signal sources drive the buffer inputs beyond the rail. The four channels map naturally to typical 4-channel or 8-channel ADC front-ends, and the 60 uA Iq keeps total system power low in battery-powered data loggers.
Empfohlen
Power Supply Current Sensing
The ADA4096-4ACPZ-R7 is well-suited for high-side or low-side current sensing in switch-mode power supplies and battery management systems. Its wide 3V-30V supply and 32V OVP accommodate the common-mode voltages seen in 12V/24V systems. The four channels can monitor multiple rails simultaneously, and the rail-to-rail output swing provides maximum dynamic range when interfacing to ADCs. The 60 uA Iq minimizes impact on overall power supply efficiency.

Wichtigste Unterscheidungsmerkmale

- 60 uA per-channel quiescent current in quad package (vs. TLV9064 (TI))
- Compact 3x3 mm LFCSP-WQ quad package (vs. ADA4096-4ARUZ)
Designhinweise
The ADA4096-4ACPZ-R7 operates from a single 3V to 30V supply or dual supplies up to +/-15V. Place a 0.1 uF ceramic decoupling capacitor within 2 mm of each supply pin (V+ pin 4 and V- pin 11), plus a bulk 1-10 uF tantalum or ceramic capacitor at the supply input. For single-supply operation, connect V- to ground. The exposed thermal pad on the underside of the LFCSP package should be soldered to a ground plane to achieve rated thermal performance and provide mechanical stability.
The 32V overvoltage protection (OVP) on the inputs allows input voltages beyond either rail, but does not eliminate the need for external protection in high-energy transient environments. Series input resistors of 10-100 kohm can limit fault current during OVP events. Avoid driving capacitive loads greater than 500 pF directly without an isolation resistor (typically 50-100 ohm in series with the output), as capacitive loading can cause instability and oscillation in op-amp circuits.
For the 16-LFCSP-WQ (3x3 mm) package, use a PCB land pattern that matches the JEDEC MO-220 recommendation. The exposed pad (EP) on pin 5 (package bottom) must be soldered to a PCB pad of at least 50% of the package footprint area for thermal dissipation. Use ground-plane stitching vias around the EP pad on 0.5-1.0 mm pitch. Keep high-impedance input traces short and guarded with grounded traces to minimize leakage and noise pickup, especially for sensor interface applications where the ADA4096-4's 60 uA Iq is a key advantage.
