Product details
Overview
AD8652ARZ-REEL7 from Analog Devices is a dual-channel, rail-to-rail input/output precision CMOS operational amplifier optimized for high-speed, low-noise signal conditioning in 2.7 V to 5.5 V single-supply systems. It delivers 50 MHz gain bandwidth, 41 V/μs slew rate, 4.5 nV/√Hz voltage noise at 100 kHz, and 90 μV typical offset voltage over full common-mode range - enabling use in laser driver feedback loops, high-resolution ADC front-ends, and broadband video line driving.
For engineers reviewing the AD8652ARZ-REEL7 datasheet, AD8652ARZ-REEL7 pinout, AD8652ARZ-REEL7 application, or AD8652ARZ-REEL7 equivalent, key selection criteria include guaranteed rail-to-rail operation across −40°C to +125°C, DigiTrim®-calibrated offset over full VCM, sub-pA input bias current (1 pA typ), and SOIC_N package compatibility with space-constrained industrial and optical communication designs.
Technical Context
The AD8652ARZ-REEL7 implements a dual-channel voltage-feedback architecture with parallel NMOS/PMOS rail-to-rail input stages, each independently trimmed via DigiTrim® to minimize offset variation across the entire common-mode range (−0.1 V to +5.1 V at 5 V supply). Its output stage uses complementary common-source MOSFETs to achieve <30 mV VOL and >4.97 V VOH at 250 µA load over temperature.
This amplifier operates without phase reversal under common-mode overvoltage conditions and features 115 dB open-loop gain (RL = 1 kΩ), 95 dB CMRR at 125°C, and 0.2 µs 0.01% settling time for 2 V step - making it suitable for precision closed-loop control where dynamic accuracy and DC stability are co-required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - supports stable unity-gain compensation up to 50 MHz, enabling wideband filtering and active equalization in 100 Mbps+ data paths. |
| Slew Rate | 41 V/μs - ensures faithful reproduction of fast transients (e.g., video sync pulses, laser modulation edges) without slew-induced distortion. |
| Voltage Noise Density | 4.5 nV/√Hz at 100 kHz - preserves SNR in low-level sensor amplification and photodiode preamp stages where thermal noise dominates. |
| Input Offset Voltage | 90 μV typical, 1.4 mV max over −40°C to +125°C - enables accurate DC-coupled gain without manual nulling in industrial process monitoring circuits. |
| Supply Current per Channel | 17.5–20.0 mA at 25°C, 23.5 mA max at 125°C - balances speed and power for dual-channel applications where thermal budget limits total dissipation. |
| Common-Mode Input Range | −0.1 V to +5.1 V at 5 V supply - allows direct interfacing to unbuffered ADC references, DAC outputs, and single-supply sensors without level-shifting. |
| Output Swing | Rail-to-rail: VOL ≤ 30 mV, VOH ≥ 4.97 V at 250 µA load - maximizes dynamic range in 5 V systems, reducing headroom loss in analog signal chains. |
Pinout & Package
AD8652ARZ-REEL7 is housed in an 8-lead narrow SOIC_N (R-8) package, RoHS-compliant and tape-and-reel packaged per JEDEC standard. Pin 1 is marked by a beveled corner or dot; pins are numbered counterclockwise from Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or feedback network; capable of sourcing/sinking 40 mA with rail-to-rail swing. |
| 2 | –IN A | Inverting input of Channel A - high-impedance node (1 pA bias current); requires guarded layout to preserve low-offset performance. |
| 3 | +IN A | Non-inverting input of Channel A - matched to –IN A for optimal CMRR; accepts signals from −0.1 V to +5.1 V at 5 V supply. |
| 4 | V– | Negative supply rail (GND for single-supply use) - must be low-impedance; bypassed with 0.1 µF ceramic capacitor placed adjacent to pin. |
| 5 | +IN B | Non-inverting input of Channel B - electrically identical to Pin 3; independent channel enables dual-path signal processing or differential drive. |
| 6 | –IN B | Inverting input of Channel B - isolated from Channel A inputs to maintain >120 dB channel separation at 100 kHz. |
| 7 | OUT B | Amplifier B output - fully independent output stage; shares no internal nodes with OUT A, supporting true dual-channel operation. |
| 8 | V+ | Positive supply rail (2.7–5.5 V) - supplies both channels; requires local 0.1 µF + 4.7 µF bypassing to suppress high-frequency PSRR degradation. |
Key Features
| Feature | Design Value |
|---|---|
| DigiTrim® In-Package Trimming | Offset voltage calibrated across full input common-mode range (−0.1 V to +5.1 V), eliminating VOS discontinuity in rail-to-rail transition zone and improving CMRR by >5 dB vs. untrimmed competitors. |
| Rail-to-Rail Input/Output | Enables full-scale signal utilization in 2.7–5.5 V systems - e.g., direct interface to 5 V ADCs without level shifters, preserving 16-bit+ ENOB in data acquisition. |
| Ultra-Low Input Bias Current | 1 pA typical (≤600 pA at 125°C) - minimizes voltage error in high-Z sensor interfaces (e.g., piezoelectric pickups, pH electrodes) and maintains accuracy with >10 MΩ source impedances. |
| Low Distortion + Noise | THD+N = 0.0006% at 1 kHz, 2 Vp-p; 4.5 nV/√Hz noise - meets audio-grade and instrumentation requirements where harmonic content and noise floor directly impact measurement fidelity. |
| Extended Temperature Range | Specified from −40°C to +125°C - validated for automotive under-hood, industrial motor control, and telecom infrastructure applications without derating. |

FAQ
What is the maximum operating temperature for AD8652ARZ-REEL7?
The AD8652ARZ-REEL7 is fully specified from −40°C to +125°C ambient temperature, with electrical parameters including offset voltage, CMRR, and supply current guaranteed across this extended industrial range. Thermal resistance θJA is 158°C/W for the SOIC_N package, enabling reliable operation in thermally demanding environments when PCB copper area and airflow meet datasheet layout guidelines.
Does AD8652ARZ-REEL7 support true rail-to-rail input and output operation?
Yes, AD8652ARZ-REEL7 supports true rail-to-rail input (VCM = −0.1 V to +5.1 V at 5 V supply) and output (VOL ≤ 30 mV, VOH ≥ 4.97 V at 250 µA load) operation. Its dual-input-stage architecture - with NMOS and PMOS pairs active across the full common-mode range and DigiTrim® calibration - eliminates crossover distortion and maintains CMRR >73 dB even near the rails.
What is the purpose of DigiTrim® technology in AD8652ARZ-REEL7?
DigiTrim® is Analog Devices' post-package trimming method that measures and corrects input offset voltage across the entire input common-mode range after assembly. For AD8652ARZ-REEL7, this ensures <90 μV typical offset and eliminates the VOS discontinuity typically seen in rail-to-rail amplifiers during NMOS/PMOS input stage transition - directly improving DC accuracy and CMRR in precision closed-loop systems.
Can AD8652ARZ-REEL7 drive a 600 Ω load at 1 kHz with low distortion?
Yes, AD8652ARZ-REEL7 achieves 0.0006% THD+N at 1 kHz with 2 Vp-p output into a 600 Ω load - meeting professional audio and instrumentation standards. This performance is enabled by its 41 V/μs slew rate, 50 MHz bandwidth, and low 4.5 nV/√Hz noise floor, ensuring minimal harmonic generation and preserved signal integrity in sensitive analog paths.
Is AD8652ARZ-REEL7 pin-compatible with other dual op amps in SOIC-8 packages?
AD8652ARZ-REEL7 follows the industry-standard dual op amp pinout (Pin 1 = OUT A, Pin 2 = –IN A, Pin 3 = +IN A, Pin 4 = V–, Pin 5 = +IN B, Pin 6 = –IN B, Pin 7 = OUT B, Pin 8 = V+), making it drop-in compatible with many SOIC-8 dual op amps such as OP27, AD8628, and OPA2350 - provided supply voltage, bandwidth, and precision requirements align with the target application.
