Product details
Overview
AD8137WYCPZ-R7 from Analog Devices is a low-cost, low-power fully differential ADC driver amplifier in an 8-lead SOIC package, featuring rail-to-rail output swing, adjustable output common-mode voltage (VOCM), and 110 MHz large-signal 3 dB bandwidth at G = 1. It delivers 450 V/µs slew rate, 100 ns settling to 0.02%, and 90 dB SFDR at 500 kHz-optimized for high-precision automotive vision systems and battery-powered instrumentation.
For engineers reviewing the AD8137WYCPZ-R7 datasheet, AD8137WYCPZ-R7 pinout, AD8137WYCPZ-R7 application, or AD8137WYCPZ-R7 equivalent, key selection criteria include its automotive-grade temperature range (−40°C to +125°C), power-down mode (450 µA quiescent current), VOCM-controlled common-mode output, and differential-to-differential or single-ended-to-differential configuration capability.
Technical Context
The AD8137WYCPZ-R7 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 balanced differential outputs. Its fully differential topology inherently suppresses even-order harmonic distortion and supports externally set gain via four-resistor feedback networks.
It operates from a wide supply range (±2.7 V to ±6 V or single 2.7 V to 12 V), with rail-to-rail output swing (VS− + 0.45 V to VS+ − 0.45 V at 5 V) and integrated power-down control (PD pin threshold: VS− + 0.7 V to VS− + 1.5 V). The device is fabricated on Analog Devices' XFCB process for low power and high-speed performance.

Pinout & Package
AD8137WYCPZ-R7 is housed in an 8-lead SOIC package (JEDEC MS-012AA, 5.0 mm × 6.2 mm, 1.27 mm pitch) with exposed paddle (EPAD) for thermal enhancement. Pin 1 is marked by notch or dot; EPAD may be connected to ground or negative supply.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input | Accepts differential or single-ended input; used with +IN to define gain and common-mode rejection |
| 2 (VOCM) | Output common-mode control | Sets average DC level of differential outputs; enables level-shifting to match ADC input range |
| 3 (VS+) | Positive supply | Supports single (2.7–12 V) or dual (±2.7–±6 V) operation; decoupling required near pin |
| 4 (+OUT) | Positive differential output | Delivers rail-to-rail swing; paired with −OUT for true differential signaling to ADC inputs |
| 5 (−OUT) | Negative differential output | Complements +OUT; internal feedback ensures amplitude and phase balance up to 1 MHz |
| 6 (VS−) | Negative supply | Required for dual-supply operation; tied to ground in single-supply configurations |
| 7 (PD) | Power-down enable | Active-low logic input; pulls quiescent current to 450 µA when asserted |
| 8 (+IN) | Noninverting input | Primary signal path input; combined with −IN defines differential input impedance (800 kΩ diff) |

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 (12.5 mA), LFCSP package only | Better suited for >50 MSPS ADCs and RF sampling; not automotive-qualified | Select AD8138ARZ when speed outweighs power and qualification requirements |
| THS4561IRGET | Lower power (1.8 mA), lower bandwidth (100 MHz), fixed VOCM = VCC/2 | Lacks external VOCM control; requires supply-dependent common-mode setting | Choose THS4561IRGET for cost-sensitive, non-automotive designs where VOCM flexibility is unnecessary |
Compared with AD8137WYCPZ-R7, AD8138ARZ trades significant power increase for >2× bandwidth and lacks automotive qualification, while THS4561IRGET reduces power but sacrifices VOCM adjustability and temperature robustness-making AD8137WYCPZ-R7 optimal for automotive and battery-constrained differential ADC interfaces requiring precision level control.

FAQ
What is the operating temperature range of the AD8137WYCPZ-R7?
The AD8137WYCPZ-R7 is rated for operation from −40°C to +125°C and is qualified for automotive applications per AEC-Q100 Grade 1. This extended range ensures reliable performance in under-hood environments and industrial settings where ambient temperatures exceed standard commercial limits. All key specifications-including bandwidth, offset voltage, and power consumption-are guaranteed across this full range.
How does the VOCM pin function in the AD8137WYCPZ-R7?
The VOCM pin on the AD8137WYCPZ-R7 sets the common-mode voltage of the differential output pair (+OUT and −OUT). An internal feedback loop forces the average of the two outputs to equal the applied VOCM voltage, enabling precise level-shifting to match the input range of downstream ADCs. For example, applying 2.5 V to VOCM centers the outputs at 2.5 V, allowing full-swing differential signals within a 0–5 V single-supply system.
Can the AD8137WYCPZ-R7 drive a 12-bit ADC effectively?
Yes, the AD8137WYCPZ-R7 delivers 90 dB SFDR at 500 kHz and 12-bit SFDR performance as stated in the datasheet, making it suitable for driving 12-bit and higher-resolution SAR and sigma-delta ADCs. Its 100 ns settling time to 0.02%, low input offset (±2.7 mV), and balanced outputs minimize code errors and harmonic distortion-critical for maintaining ENOB in precision measurement systems.
What is the power-down behavior of the AD8137WYCPZ-R7?
When the PD pin is pulled low (≤ VS− + 0.7 V), the AD8137WYCPZ-R7 enters power-down mode, reducing quiescent current to 450 µA at 5 V supply. Output stages are disabled, placing +OUT and −OUT in high-impedance state. Recovery time from power-down is not specified, but normal operation resumes within microseconds after PD returns high; no reset sequence is required.
Is the AD8137WYCPZ-R7 compatible with single-ended input sources?
Yes, the AD8137WYCPZ-R7 supports single-ended-to-differential conversion. With +IN grounded and signal applied to −IN (or vice versa), and appropriate resistor feedback network (e.g., RG = RF), it achieves gain G = 1 + RF/RG while rejecting common-mode noise. The internal common-mode feedback maintains output balance and VOCM tracking, preserving performance without external baluns or transformers.
