Product details
Overview
AD8137YR-REEL7 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 via VOCM pin. It supports single-ended-to-differential or differential-to-differential conversion and operates from ±5 V or +2.7 V to +12 V supplies - ideal for battery-powered instrumentation and automotive vision systems.
For engineers reviewing the AD8137YR-REEL7 datasheet, AD8137YR-REEL7 pinout, AD8137YR-REEL7 application, or AD8137YR-REEL7 equivalent, key selection criteria include its 2.6 mA quiescent current at 5 V, 100 ns settling time to 0.02%, 12-bit SFDR at 500 kHz, power-down capability (450 µA), and SOIC-8 packaging with exposed paddle for thermal management.
Technical Context
The AD8137YR-REEL7 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 inherent output balance. Its fully differential topology suppresses even-order harmonics and provides high CMRR (79 dB typical) and PSRR (91 dB).
Gain is set externally using four resistors (RF/RG network), supporting configurable closed-loop gains (G = 1 to 10). The power-down pin (PD) disables the amplifier, reducing supply current to 450 µA at 5 V - critical for portable and automotive infotainment systems requiring dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Large-signal BW | 110 MHz @ 2 Vp-p, G = 1 - enables high-fidelity signal conditioning for >10 MSPS ADCs. |
| Slew rate | 450 V/µs - supports fast transient response without distortion in wideband applications. |
| Settling time | 100 ns to 0.02% - ensures accurate sampling for 12-bit+ ADCs with minimal acquisition delay. |
| Quiescent current | 2.6 mA @ 5 V - balances performance and battery life in portable instrumentation. |
| Power-down current | 450 µA @ 5 V - reduces system standby power without external circuitry. |
| Input offset voltage | ±2.6 mV max - minimizes DC error in precision sensor front-ends and measurement systems. |
| Output swing | Rail-to-rail (VS− + 0.45 V to VS+ − 0.45 V @ 5 V) - maximizes dynamic range into ADC inputs. |
Pinout & Package
AD8137YR-REEL7 is housed in an 8-lead SOIC package with exposed paddle (EPAD) for enhanced thermal performance. The EPAD may be connected to ground or power plane per PCB layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input | Differential input node; used with +IN to define gain and common-mode rejection path. |
| 2 (VOCM) | Output common-mode control | Sets DC level of differential output pair; enables level-shifting to match ADC input range. |
| 3 (VS+) | Positive supply | Accepts +2.7 V to +12 V or ±6 V; supports single- or dual-supply operation. |
| 4 (+OUT) | Positive differential output | Delivers inverted complement of −OUT; requires matched routing for balanced signal integrity. |
| 5 (−OUT) | Negative differential output | Delivers inverted complement of +OUT; forms fully differential output pair with +OUT. |
| 6 (VS−) | Negative supply | Ground or negative rail; required for dual-supply operation or referenced to ground in single-supply mode. |
| 7 (PD) | Power-down enable | Logic-low assertion disables amplifier core, reducing IQ to 450 µA - no external sequencing needed. |
| 8 (+IN) | Noninverting input | Differential input node; defines reference for VOCM-controlled output common-mode voltage. |

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), higher power (10.5 mA), integrated resistor network for fixed gains. | Better suited for >50 MSPS ADCs and RF sampling; less optimal for ultra-low-power portable use. | Select AD8138ARZ when bandwidth >200 MHz is required and power budget allows ≥10 mA. |
| THS4561IRGET | Lower quiescent current (1.1 mA), lower slew rate (210 V/µs), smaller 12-pin QFN package. | Optimized for cost-sensitive, space-constrained industrial DAQ; not AEC-Q100 qualified. | Choose THS4561IRGET for non-automotive, high-density PCBs where 110 MHz BW is sufficient and <2 mA IQ is mandatory. |
Compared with AD8137YR-REEL7, AD8138ARZ trades power efficiency for bandwidth headroom, while THS4561IRGET reduces size and current but sacrifices automotive qualification and slew rate - making AD8137YR-REEL7 the optimal balance for cost-sensitive, AEC-Q100-compliant, medium-speed ADC driving.

FAQ
What is the operating temperature range of the AD8137YR-REEL7?
The AD8137YR-REEL7 is rated for operation from −40°C to +125°C, meeting extended industrial and automotive under-hood requirements. This range is validated across all electrical specifications in the datasheet, including quiescent current, bandwidth, and offset voltage drift, ensuring reliability in harsh environments where the AD8137YR-REEL7 is deployed.
Does the AD8137YR-REEL7 require external compensation components?
No, the AD8137YR-REEL7 is internally compensated and stable with standard 4-resistor feedback networks. External capacitors (e.g., CF) may be added to optimize transient response or reduce peaking, but are not required for stability - simplifying design and reducing BOM count for the AD8137YR-REEL7 in production systems.
Can the AD8137YR-REEL7 drive ADCs with >12-bit effective resolution?
Yes - the AD8137YR-REEL7 delivers 12-bit SFDR at 500 kHz and maintains >89 dB SFDR up to 2 MHz, with low input voltage noise (8.25 nV/√Hz) and high open-loop gain (89 dB). These characteristics enable clean signal conditioning for 12-bit+ SAR and sigma-delta ADCs when paired with proper layout and filtering for the AD8137YR-REEL7.
How is the output common-mode voltage controlled on the AD8137YR-REEL7?
The AD8137YR-REEL7 uses the VOCM pin (Pin 2) to set output common-mode voltage: the internal feedback loop forces the average of +OUT and −OUT to equal the applied VOCM voltage. At 5 V supply, VOCM accepts 1 V to 4 V, enabling precise matching to ADC input ranges - a core functional feature of the AD8137YR-REEL7 not dependent on external resistors.
Is the AD8137YR-REEL7 pin-compatible with other members of the AD813x family?
No - the AD8137YR-REEL7 shares the same 8-lead SOIC footprint as AD8138, but pin functions differ: AD8138 has dedicated REF pins instead of VOCM and PD, and lacks power-down functionality. Direct substitution is not supported; circuit redesign is required when migrating between AD8137YR-REEL7 and AD8138 or AD8136 variants.
