Product details
Overview
ICL7652BCPD from Maxim Integrated is a precision chopper-stabilized operational amplifier in 14-pin PDIP package, featuring 10µV max input offset voltage, 0.1µV/°C max offset drift, and 1.5MHz gain-bandwidth product. It serves as a low-drift signal conditioning amplifier in high-accuracy thermocouple interfaces and strain-gauge instrumentation.
For engineers reviewing the ICL7652BCPD datasheet, ICL7652BCPD pinout, ICL7652BCPD application, or ICL7652BCPD equivalent, key selection criteria include ultra-low offset drift over temperature, chopper stabilization architecture for DC accuracy, and compatibility with single-supply or dual-supply configurations in precision analog front-ends.
Technical Context
The ICL7652BCPD uses a two-stage chopper-stabilized topology with internal auto-zeroing to cancel input offset and 1/f noise. Its architecture includes a main amplifier and a separate chopper amplifier that periodically measures and corrects offset at 10kHz.
It operates from ±2V to ±18V supplies, delivers ±12V output swing into 10kΩ, and maintains stability without external compensation. The device is specified over 0°C to 70°C (Commercial) temperature range with guaranteed parameters at 25°C.
Key Specifications

| Offset Drift | 0.1 µV/°C max - Ensures <1 µV total drift across 0–70°C industrial ambient range |
| Gain-Bandwidth Product | 1.5 MHz - Supports stable closed-loop gain up to 100 at 10kHz signal bandwidth |
| Supply Voltage Range | ±2 V to ±18 V - Compatible with legacy ±5V, ±12V, and ±15V analog rails |
| Output Swing | ±12 V min into 10 kΩ - Delivers full dynamic range for 12-bit ADC interfacing |
| CMRR | 120 dB min - Rejects common-mode noise in bridge-based transducer circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision chopper-stabilized op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8551ARZ | Single-supply only (2.7–5.5V); 1µV offset; no strobe pin | Limited to low-voltage systems; lacks external chopper sync capability | Prefer ICL7652BCPD when dual-supply operation or strobe control is required |
| LTC1052CN8#PBF | 8-pin SOIC; 5µV offset; 1.2MHz GBW; no offset null pins | Smaller footprint but no manual offset trimming; lower bandwidth | Choose ICL7652BCPD for applications needing adjustable nulling or higher bandwidth |
Compared with AD8551ARZ and LTC1052CN8#PBF, the ICL7652BCPD offers wider supply flexibility, user-adjustable offset nulling, and external strobe synchronization-critical for legacy industrial designs and metrology-grade calibration systems where long-term DC stability and configurability are prioritized over package size or single-supply convenience.

FAQ
What is the operating temperature range for the ICL7652BCPD?
ICL7652BCPD is rated for commercial operation from 0°C to +70°C. All key specifications-including input offset voltage, offset drift, and gain-bandwidth-are guaranteed across this full range, with typical performance characterized at 25°C. It is not qualified for extended or industrial temperature grades.
Does the ICL7652BCPD require external capacitors for stability?
No, the ICL7652BCPD is internally compensated and remains stable in unity-gain and higher closed-loop configurations without external frequency compensation components. This simplifies PCB layout and eliminates tuning steps during design validation of the ICL7652BCPD.
Can the ICL7652BCPD operate from a single supply?
Yes, the ICL7652BCPD supports single-supply operation-for example, with V+ = +15V and V– = 0V-but its input common-mode and output swing ranges are optimized for dual-supply use. When using single supply, ensure input signals remain within the specified common-mode range and verify output headroom against load requirements for the ICL7652BCPD.
What is the function of the Strobe and Strobe Return pins on the ICL7652BCPD?
The Strobe pin (Pin 5) accepts an external TTL/CMOS clock to synchronize the internal chopper switching cycle; Strobe Return (Pin 14) provides the return path. If unused, Strobe should be left open and Strobe Return tied to ground. This feature prevents beat frequencies in the ICL7652BCPD when used alongside other clocked systems like ADCs or PWM controllers.
How does the ICL7652BCPD differ from standard op-amps in sensor interface applications?
The ICL7652BCPD uses chopper stabilization to achieve microvolt-level input offset and sub-0.1µV/°C drift-orders of magnitude better than general-purpose op-amps. This enables direct DC coupling and long-term accuracy in sensor interfaces such as thermocouples and strain gauges, where the ICL7652BCPD replaces traditional auto-zero or discrete chopper solutions.
