Product details
Overview
AD8137YRZ-REEL from Analog Devices is a low-cost, low-power fully differential ADC driver amplifier with rail-to-rail output, 110 MHz large-signal bandwidth, 450 V/µs slew rate, and adjustable output common-mode voltage (VOCM). It operates from ±5 V or single 3–12 V supplies and delivers 12-bit SFDR performance at 500 kHz in battery-powered instrumentation and automotive vision systems.
For engineers reviewing the AD8137YRZ-REEL datasheet, AD8137YRZ-REEL pinout, AD8137YRZ-REEL application, or AD8137YRZ-REEL equivalent, key selection criteria include differential-to-differential conversion capability, power-down mode (450 µA quiescent current), VOCM-controlled common-mode output, and SOIC-8 packaging for space-constrained signal conditioning front-ends.
Technical Context
The AD8137YRZ-REEL employs an internal common-mode feedback architecture that forces the output common-mode voltage to track the VOCM pin voltage, enabling precise level shifting and rejection of even-order harmonics. Its fully differential topology supports both differential-input/differential-output and single-ended-input/differential-output configurations using external resistor networks.
Gain is set externally via four resistors (RF/RG), allowing flexible closed-loop gain adjustment from G = 1 to G = 10. The power-down pin (PD) disables the amplifier core, reducing supply current to ≤600 µA while maintaining fast wake-up response (<100 ns overdrive recovery).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Large-signal BW | 110 MHz @ 2 V p-p output - supports high-speed ADC sampling up to ~55 MSPS with minimal gain roll-off. |
| Slew rate | 450 V/µs - enables clean reproduction of fast transient signals without slewing distortion in wideband applications. |
| Settling time | 100 ns to 0.02% - meets timing budgets for 12-bit+ successive-approximation ADC drivers. |
| Quiescent current | 2.6 mA @ 5 V - enables low-power operation in portable and automotive infotainment systems. |
| Power-down current | 450 µA @ 5 V - reduces system standby power without requiring reconfiguration on wake-up. |
| Input offset voltage | ±2.6 mV max - minimizes DC error contribution in precision sensor signal chains before ADC. |
| Output swing | Rail-to-rail (VS− + 0.45 V to VS+ − 0.45 V @ 5 V) - maximizes dynamic range into modern low-voltage ADC inputs. |
Pinout & Package
AD8137YRZ-REEL is housed in an 8-lead SOIC package (SOIC_N, 150 mil width) with exposed paddle (EPAD) for thermal enhancement. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input | Accepts negative-phase analog input; used with +IN to configure differential input or with feedback network for single-ended input. |
| 2 (VOCM) | Output common-mode control | Sets DC level of differential output pair; drives ADC reference mid-point or matches downstream stage bias. |
| 3 (VS+) | Positive supply | Supports single-supply (2.7–12 V) or dual-supply (±2.7–±6 V) operation; decoupling required near pin. |
| 4 (+OUT) | Positive differential output | Delivers inverted or noninverted signal depending on configuration; pairs with −OUT for balanced drive. |
| 5 (−OUT) | Negative differential output | Complements +OUT to form true differential output; critical for CMRR and harmonic suppression. |
| 6 (VS−) | Negative supply | Required for dual-supply operation; tied to ground in single-supply mode (VS− = 0 V). |
| 7 (PD) | Power-down enable | Active-low logic input; pulls amplifier core into ultra-low-current state when driven < VS− + 0.7 V. |
| 8 (+IN) | Noninverting input | Primary signal input node; combined with −IN for differential input or used alone for single-ended configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Provides inherent even-order harmonic cancellation and >64 dB output balance error at 1 MHz for clean ADC input spectra. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential ADC driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8138ARZ | Higher bandwidth (320 MHz large-signal), higher supply current (12.5 mA), same SOIC-8 package and VOCM architecture. | Targeted at >100 MSPS ADCs and RF sampling applications where speed outweighs power budget. | Select AD8138ARZ when system requires >2× bandwidth and can accommodate 5× higher quiescent power. |
| THS4561IRGET | Lower noise (4.3 nV/√Hz), lower distortion (−92 dBc SFDR @ 10 MHz), 3 mm × 3 mm QFN-16 package, no power-down pin. | Preferred for high-fidelity audio or precision measurement where SNR dominates over power and board area. | Select THS4561IRGET when ultra-low noise and distortion are mandatory and SOIC-8 footprint is not required. |
Compared with AD8137YRZ-REEL, AD8138ARZ trades 5× higher power for 3× bandwidth, while THS4561IRGET offers superior noise performance in a smaller package but lacks power-down functionality-making AD8137YRZ-REEL optimal for cost-sensitive, battery-operated, medium-speed ADC interfaces.

FAQ
What is the operating temperature range for the AD8137YRZ-REEL?
The AD8137YRZ-REEL is rated for operation from −40°C to +125°C, meeting AEC-Q100 stress test requirements for automotive applications. This extended industrial temperature range ensures reliability in under-hood camera modules, engine control sensor interfaces, and industrial data acquisition systems exposed to harsh thermal environments. The AD8137YRZ-REEL maintains specified performance across this full range per Rev. E datasheet Table 1–3.
Does the AD8137YRZ-REEL support single-ended input configurations?
Yes, the AD8137YRZ-REEL supports single-ended-to-differential conversion using standard external resistor networks. With +IN grounded or biased and signal applied to −IN (or vice versa), the device generates a balanced differential output referenced to the VOCM pin voltage. Application Note AN-1102 confirms this configuration achieves >64 dB output balance and 12-bit SFDR performance at 500 kHz - identical to its differential-input operation.
How does the VOCM pin function in the AD8137YRZ-REEL?
The VOCM pin on the AD8137YRZ-REEL directly controls the common-mode voltage of the differential output pair. An internal feedback loop forces VO,cm = VOCM over frequency (60 MHz −3 dB bandwidth) and load conditions. This allows precise alignment of the output midpoint to match ADC input requirements (e.g., 0.9 V for a 1.8 V supply) without external op amps or resistive dividers - simplifying layout and improving DC accuracy in the AD8137YRZ-REEL signal chain.
What is the minimum supply voltage for the AD8137YRZ-REEL?
The AD8137YRZ-REEL operates from a minimum total supply voltage of 2.7 V, supporting single-supply configurations (e.g., VS+ = 2.7 V, VS− = 0 V) or split supplies (e.g., ±1.35 V). At 2.7 V, it delivers 93 MHz large-signal bandwidth, 340 V/µs slew rate, and 2.5 mA quiescent current - enabling functional operation in ultra-low-voltage portable systems while maintaining usable performance margins.
Is the AD8137YRZ-REEL pin-compatible with other members of the AD813x family?
No, the AD8137YRZ-REEL is not pin-compatible with AD8138 or AD8139. While all share the same 8-lead SOIC footprint and VOCM-based architecture, AD8138/AD8139 feature different pin assignments (e.g., PD pin relocated or omitted) and internal compensation. Substituting without board revision risks incorrect biasing or loss of power-down functionality. Always verify pin mapping against the specific device's Rev. E datasheet Figure 4 before replacement.
