Product details
Overview
AD8132WARMZ-R7 from Analog Devices is an automotive-grade, high-speed differential amplifier optimized for single-ended-to-differential conversion in ADC driver and video signal chain applications. It delivers 350 MHz −3 dB bandwidth (±5 V), 1200 V/μs slew rate, −99 dBc SFDR at 5 MHz (800 Ω load), and resistor-set gain with independent VOCM control. Its AEC-Q100 qualification supports operation from −40°C to +125°C in automotive infotainment and ADAS sensor interfaces.
For engineers reviewing the AD8132WARMZ-R7 datasheet, AD8132WARMZ-R7 pinout, AD8132WARMZ-R7 application, or AD8132WARMZ-R7 equivalent, key selection criteria include differential output balance (−68 dB @ 10 MHz), VOCM-controlled common-mode level shifting, low distortion in single-supply ADC driver configurations, and MSOP-8 packaging for space-constrained automotive modules.
Technical Context
The AD8132WARMZ-R7 employs internal common-mode feedback to enforce precise gain and phase matching between differential outputs, achieving −68 dB balance error at 10 MHz. Its architecture enables direct drive of differential-input ADCs without transformers while preserving DC and low-frequency content.
It supports flexible supply configurations (±1.35 V to ±5.5 V or +2.7 V to +11 V), features separate VOCM input for output common-mode voltage setting (1:1 ratio), and maintains stable performance across temperature with <10 μV/°C offset drift and −60 dB CMRR over full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 350 MHz at ±5 V supply, enabling high-fidelity analog video and wideband data transmission up to ~175 MHz Nyquist. |
| Slew Rate | 1200 V/μs, supporting fast transient response for 10-bit+ ADC sampling without slewing-induced distortion. |
| Output Balance Error | −68 dB @ 10 MHz, minimizing even-order harmonics and EMI radiation in balanced line driving. |
| Input Voltage Noise | 8 nV/√Hz (RTI), critical for maintaining SNR in low-amplitude sensor or precision ADC front-end stages. |
| Quiescent Current | 10.7 mA @ 5 V, enabling low-power operation in always-on automotive subsystems without thermal derating. |
| Operating Temperature | −40°C to +125°C, fully qualified per AEC-Q100 Grade 1 for under-hood and display module deployment. |
| Package | 8-lead MSOP (ARMZ), 3 mm × 3 mm footprint with exposed pad for thermal management in compact PCB layouts. |
Pinout & Package
AD8132WARMZ-R7 uses an 8-lead MSOP package (ARMZ suffix) with exposed thermal pad. Pin 7 is NC; all other pins are electrically active and functionally defined per Analog Devices' official pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: −IN | Negative input terminal | Inverts applied signal at +OUT; forms differential input pair with +IN for common-mode rejection. |
| 2: VOCM | Common-mode output voltage control | DC voltage applied here sets both +OUT and −OUT bias levels at 1:1 ratio-enables level-shifting into single-supply ADCs. |
| 3: V+ | Positive supply rail | Accepts +2.7 V to +11 V (single supply) or up to +5.5 V (dual supply); decoupling required within 1 cm. |
| 4: +OUT | Positive differential output | Provides inverted replica of −IN signal; must be terminated differentially (e.g., 499 Ω across +OUT/−OUT). |
| 5: −OUT | Negative differential output | Provides inverted replica of +IN signal; complements +OUT to deliver true differential swing with matched timing. |
| 6: V− | Negative supply rail | Required for dual-supply operation (±1.35 V to ±5.5 V); tied to GND in single-supply mode with VOCM biasing. |
| 8: +IN | Positive input terminal | Non-inverting input referenced to VOCM; used with −IN to configure gain via external resistors RF/RG. |
Key Features
| Feature | Design Value |
|---|---|
| Resistor-set gain configuration | Gain = 1 + RF/RG with no internal gain-setting resistors-supports precise, application-specific gain from +1 to +10. |
| Internal common-mode feedback loop | Actively matches output amplitude and phase to −68 dB @ 10 MHz, eliminating need for external trimming or calibration. |
| Separate VOCM input | Enables independent control of output common-mode level without affecting differential gain or bandwidth. |
| Fast overload recovery | 5 ns recovery time after overdrive ensures accurate sampling in high-speed ADC interfaces with transient input signals. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use at 125°C junction temperature with extended reliability testing per stress test conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4561IRGET | Lower power (6.5 mA), lower bandwidth (1.8 GHz small-signal), no VOCM pin-requires external common-mode bias network. | Better suited for battery-powered portable instrumentation; lacks AEC-Q100 qualification and automotive temp range. | Select when ultra-low quiescent current and higher small-signal bandwidth outweigh VOCM flexibility and automotive compliance. |
| LMH5401RTVT | Higher bandwidth (4.2 GHz), integrated RFI filtering, fixed +1 gain-no resistor-set gain or VOCM adjustment capability. | Optimized for RF/IF differential signaling; not intended for precision DC-coupled ADC driving or video gain control. | Choose for GHz-range communications where gain stability and EMI immunity supersede configurability and low-frequency accuracy. |
Compared with THS4561IRGET and LMH5401RTVT, AD8132WARMZ-R7 uniquely combines AEC-Q100 qualification, resistor-set gain, VOCM control, and 350 MHz large-signal bandwidth in a thermally enhanced MSOP package-making it the only option for cost-sensitive, high-reliability automotive ADC driver designs requiring DC coupling and level shifting.

FAQ
What is the maximum operating temperature for AD8132WARMZ-R7?
The AD8132WARMZ-R7 is rated for continuous operation from −40°C to +125°C ambient temperature and is AEC-Q100 Grade 1 qualified. Its junction temperature must not exceed 150°C, and thermal design must account for 142°C/W θJA in the MSOP-8 package on a 4-layer board.
Does AD8132WARMZ-R7 support single-supply operation?
Yes, AD8132WARMZ-R7 operates from +2.7 V to +11 V single supply. The VOCM pin allows setting output common-mode voltage independently-e.g., 1.25 V for driving 2.5 V ADCs-while maintaining full dynamic range and specified bandwidth.
What is the purpose of the VOCM pin on AD8132WARMZ-R7?
The VOCM pin on AD8132WARMZ-R7 sets the DC bias level of both +OUT and −OUT with 1:1 tracking. Applying 2.5 V to VOCM centers the differential output swing at 2.5 V, enabling direct interfacing with single-supply ADCs without AC coupling or level-shifting circuitry.
Can AD8132WARMZ-R7 drive a 150 Ω differential load?
Yes, AD8132WARMZ-R7 can drive 150 Ω differential loads (e.g., video lines) with verified performance: differential gain error ≤0.025% and phase error ≤0.15° at NTSC frequencies when configured for G = +2 with appropriate feedback resistors.
Is AD8132WARMZ-R7 pin-compatible with standard AD8132 variants?
Yes, AD8132WARMZ-R7 shares identical pinout and electrical behavior with non-automotive AD8132 variants in the same MSOP-8 package (ARMZ), including AD8132ARMZ-R7. Only temperature rating and qualification differ-no PCB redesign is needed for drop-in replacement in automotive designs.
