Product details
Overview
AD8032BRZ-REEL7 from Analog Devices is a dual, rail-to-rail input/output voltage feedback operational amplifier optimized for high-speed, low-power applications. It delivers 80 MHz −3 dB bandwidth (G = +1), 30 V/μs slew rate, and 125 ns settling time to 0.1% while consuming only 800 μA per amplifier at +5 V supply. It operates from +2.7 V to +12 V single supply or ±1.35 V to ±6 V dual supply and is widely used as an A/D converter buffer in portable instrumentation.
For engineers reviewing the AD8032BRZ-REEL7 datasheet, AD8032BRZ-REEL7 pinout, AD8032BRZ-REEL7 application, or AD8032BRZ-REEL7 equivalent, key selection criteria include rail-to-rail I/O swing (within 20 mV of rails), low distortion (−62 dBc @ 1 MHz), crosstalk performance (−60 dB @ 5 MHz), and guaranteed operation across −40°C to +85°C industrial temperature range.
Technical Context
The AD8032BRZ-REEL7 employs a proprietary eXtra Fast Complementary Bipolar (XFCB) process enabling simultaneous high speed and low quiescent current. Its input stage dynamically switches between PNP and NPN differential pairs to extend common-mode range beyond rails by 200 mV without phase reversal up to 500 mV beyond supplies.
The rail-to-rail output stage uses common-emitter transistors with ~25 Ω collector resistance, delivering 15 mA output current and maintaining open-loop gain stability within 250 mV of VCC and 150 mV of VEE. Distortion exhibits a characteristic peak near VCC − 0.7 V due to input-stage architecture, not output saturation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 80 MHz at G = +1: supports >10 MSPS sampling in ADC driver applications with minimal gain peaking. |
| Slew Rate | 30 V/μs: enables full-scale 2 V step response in ≤67 ns, critical for fast-settling data acquisition systems. |
| Supply Current | 800 μA per amplifier at +5 V: achieves 4 mW total power for dual channel, extending battery life in portable test equipment. |
| Input CMVR | −0.2 V to +5.2 V on +5 V supply: accepts signals 200 mV beyond rails, simplifying level-shifting in single-supply sensor interfaces. |
| Output Swing | Within 20 mV of either rail (RL = 10 kΩ): maximizes dynamic range for 12-bit+ ADCs without external biasing. |
| Crosstalk | −60 dB @ 5 MHz (dual channel): ensures channel isolation in dual-path signal conditioning without guard traces. |
| THD | −62 dBc @ 1 MHz, 2 Vp-p: meets SNR requirements for 10-bit ENOB in wideband analog front-ends. |
Pinout & Package
AD8032BRZ-REEL7 is packaged in an 8-lead SOIC_N (R) with exposed pad, rated for −40°C to +85°C operation. Pin 1 is OUT1, Pin 2 is −IN1, Pin 3 is +IN1, Pin 4 is −VS, Pin 5 is +IN2, Pin 6 is −IN2, Pin 7 is OUT2, Pin 8 is +VS. No pins are internally connected (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 (Pin 1) | Amplifier 1 output | Drives load directly; rail-to-rail swing enables direct interface to SAR ADC reference inputs. |
| −IN1 (Pin 2) | Inverting input, Amp 1 | Differential node for feedback networks; 1.6 pF input capacitance limits high-Z filter design above 10 MHz. |
| +IN1 (Pin 3) | Non-inverting input, Amp 1 | Accepts rail-to-rail common-mode signals; 40 MΩ input resistance minimizes bias current errors in high-impedance sensors. |
| −VS (Pin 4) | Negative supply rail | Connects to ground (single supply) or negative rail; must be low-impedance to maintain PSRR >75 dB. |
| +IN2 (Pin 5) | Non-inverting input, Amp 2 | Independent channel input; identical specs to Amp 1 enable matched dual-path filtering without calibration. |
| −IN2 (Pin 6) | Inverting input, Amp 2 | Shared feedback path possible with careful layout to avoid crosstalk degradation below −60 dB. |
| OUT2 (Pin 7) | Amplifier 2 output | Simultaneous dual-channel output capability supports stereo audio or differential ADC drivers. |
| +VS (Pin 8) | Positive supply rail | Accepts 2.7–12 V; 800 μA quiescent current per amp scales linearly-critical for thermal budget in dense PCB layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables true single-supply operation down to +2.7 V with full signal swing, eliminating level-shifting components in battery-powered systems. |
| 80 MHz bandwidth at 800 μA | Delivers video-bandwidth signal fidelity while consuming <4 mW total, outperforming legacy op-amps by 3× power efficiency at same speed. |
| No phase reversal to 500 mV beyond rails | Prevents catastrophic latch-up during overvoltage transients in sensor front-ends, reducing need for external clamping diodes. |
| −60 dB crosstalk at 5 MHz | Supports independent dual-channel processing (e.g., I/Q demodulation) without inter-channel interference in RF receiver designs. |
| Specified from −40°C to +85°C | Guarantees parametric performance across industrial temperature range, enabling use in automotive cabin electronics and factory automation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4891-2ARZ-R7 | Lower bandwidth (220 MHz), higher supply current (3.2 mA per amp), same SOIC-8 package. | Better for >100 MSPS ADC buffering but increases power budget by 4×. | Select when bandwidth >100 MHz is required and power is secondary to speed. |
| OPA2350UA/2K5 | Lower bandwidth (38 MHz), lower distortion (−80 dBc @ 100 kHz), same rail-to-rail I/O and SOIC-8 footprint. | Optimized for precision DC-coupled sensor interfaces, not wideband AC signals. | Select when THD <−75 dBc is mandatory and bandwidth ≤40 MHz suffices. |
Compared with ADA4891-2ARZ-R7 and OPA2350UA/2K5, AD8032BRZ-REEL7 uniquely balances 80 MHz bandwidth, 800 μA quiescent current, and −60 dB crosstalk in a standard SOIC-8, making it optimal for portable wideband instrumentation where power, size, and channel matching are co-constrained.

FAQ
What supply voltage range does the AD8032BRZ-REEL7 support?
The AD8032BRZ-REEL7 operates from +2.7 V to +12 V single supply or ±1.35 V to ±6 V dual supply. At +2.7 V, it maintains 54 MHz bandwidth and 800 μA typical quiescent current per amplifier. Performance is fully specified at +2.7 V, +5 V, and ±5 V, with no derating required across the full industrial temperature range (−40°C to +85°C). The AD8032BRZ-REEL7 remains functional up to 12.6 V absolute maximum supply rating.
Does the AD8032BRZ-REEL7 require external compensation for unity-gain stability?
No, the AD8032BRZ-REEL7 is internally compensated for unity-gain stability across all supply voltages and load conditions up to 15 pF capacitive load. The datasheet confirms stable operation with G = +1 configuration and RL = 1 kΩ without added compensation components. This eliminates external RC networks in buffer applications, reducing BOM count and PCB area for the AD8032BRZ-REEL7.
How does the AD8032BRZ-REEL7 handle input overvoltage conditions beyond the supply rails?
The AD8032BRZ-REEL7 tolerates input common-mode voltages up to 500 mV beyond either supply rail without phase reversal, enabled by its dual-input-stage architecture. However, sustained differential input voltages exceeding ±3.4 V risk damaging internal transistors. For transient overvoltage protection, external clamp diodes to rails are recommended. The AD8032BRZ-REEL7's input stage transitions smoothly between PNP and NPN pairs within a 180 mV window, avoiding abrupt parameter shifts.
What is the maximum output current drive capability of the AD8032BRZ-REEL7?
The AD8032BRZ-REEL7 delivers ±15 mA continuous output current per amplifier. Short-circuit current is +28 mA (sourcing) and −46 mA (sinking) at +5 V supply. Output swing degrades linearly with load: at RL = 1 kΩ, it swings to within 0.1 V of rails; at RL = 10 kΩ, within 20 mV. Driving >15 mA requires external boost circuitry, as the internal output stage saturates beyond this limit. This specification applies identically to both channels of the AD8032BRZ-REEL7.
Is the AD8032BRZ-REEL7 suitable for driving ADC inputs with high capacitive loads?
Yes, the AD8032BRZ-REEL7 is characterized to drive up to 15 pF capacitive loads while maintaining stability and specified settling time (125 ns to 0.1%). For ADCs with larger input capacitance (e.g., >20 pF), a series resistor (10–50 Ω) between AD8032BRZ-REEL7 output and ADC input is recommended to isolate the capacitive load and preserve phase margin. Layout best practices-short traces, ground plane, and local decoupling-further optimize performance for the AD8032BRZ-REEL7 in ADC buffer roles.
