Product details

Overview

ADHV4702-1BCPZ-R7 from Analog Devices is a 220 V, unity-gain stable precision operational amplifier designed for high-voltage signal conditioning in demanding analog front-ends. It delivers ±108.5 V output swing, 170 dB open-loop gain, 160 dB CMRR, 74 V/µs slew rate, and 2 pA max input bias current - enabling accurate high-side current sensing and LiDAR APD biasing at industrial temperatures (−40°C to +85°C).

For engineers reviewing the ADHV4702-1BCPZ-R7 datasheet, ADHV4702-1BCPZ-R7 pinout, ADHV4702-1BCPZ-R7 application, or ADHV4702-1BCPZ-R7 equivalent, key selection criteria include its 24 V to 220 V operating range, resistor-adjustable quiescent current (0.6–3.3 mA), thermal monitoring output, shutdown control, and IEC 61010-1 compliant 7 mm × 7 mm LFCSP package with exposed pad.

Technical Context

The ADHV4702-1BCPZ-R7 employs a proprietary high-voltage process enabling symmetrical (±12 V to ±110 V) or asymmetrical (up to 220 V total span) operation while maintaining precision DC performance: 1 mV max input offset voltage, 2 µV/°C max drift, and 8 nV/√Hz input voltage noise at 10 kHz. Its input common-mode range extends to within 3 V of either rail, supporting high-side sensing across wide supply configurations.

Internally, it integrates a temperature monitor (TMP) pin with −4.5 mV/°C drift, active shutdown (SD, active-low referenced to DGND), external compensation (COMP), and resistor-adjustable quiescent current (RADJ) - allowing dynamic trade-offs between bandwidth, power, and thermal management without redesigning feedback networks.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Range	24 V to 220 V total span; supports ±12 V to ±110 V dual supplies or single-supply up to 175 V - enables direct integration into HV test equipment and APD bias rails.
Output Swing	±108.5 V into 5 kΩ at ±110 V supplies - delivers full-scale precision output near supply rails for maximum dynamic range in HV DAC buffers.
Open-Loop Gain	170 dB typical (±110 V) - ensures <1 ppm gain error in closed-loop configurations requiring ultra-stable amplification.
Slew Rate	74 V/µs typical (AV = 20, 200 V p-p) - supports fast transient response in LiDAR pulse drivers and ATE step-response testing.
Input Bias Current	2 pA maximum at 25°C - preserves accuracy in high-impedance sensor interfaces like piezotransducers and photodiode TIA feedback paths.
CMRR	160 dB typical (−70 V to +70 V) - rejects supply and ground noise in noisy industrial HV environments during high-side current measurement.
Quiescent Current	0.6 mA to 3.3 mA, adjustable via RADJ resistor - allows optimization for battery-powered portable test gear or continuous-duty HV drivers.

Pinout & Package

ADHV4702-1BCPZ-R7 is housed in a 12-lead, 7 mm × 7 mm LFCSP with exposed thermal pad (EPAD), compliant with IEC 61010-1 creepage/clearance requirements for 220 V systems. The EPAD must be connected to 0 V analog ground for thermal management and high-voltage isolation.

Pin/Terminal	Circuit Role	Design Meaning
1, 3	RESERVED	Internally connected; float or tie to DGND - no functional circuit role, but grounding prevents floating node instability.
2	IN+	Noninverting input - accepts high-impedance signals up to ±107 V common-mode; critical for precision differential sensing topologies.
4	VEE	Negative power supply input - supports rail-to-rail operation down to −175 V relative to GND in asymmetrical configurations.
5	TMP	Temperature monitor analog output - provides 1.9 V at 25°C with −4.5 mV/°C slope for real-time die temperature tracking and overtemperature protection.
6	OUT	Amplifier output - delivers 20 mA typical drive into resistive loads; supports capacitive loads with external COMP pin compensation.
7	VCC	Positive power supply input - rated up to +180 V absolute maximum; requires local decoupling per high-voltage guard ring guidelines.
8	SD	Shutdown control (active low) - pulls quiescent current to 0.2 mA when driven ≤0.8 V, enabling power cycling in battery-operated HV modules.
9	RADJ	Quiescent current adjustment - connects to DGND via resistor (0 Ω to 100 kΩ) to set IQ from 0.6 mA to 3.3 mA for thermal/power tuning.
10	DGND	Digital ground reference - ties RADJ and SD logic thresholds to AGND; must be connected to 0 V analog ground for proper biasing.
11	COMP	External compensation node - allows stability optimization for varying gains and capacitive loads; required for >10 MHz small-signal bandwidth.
12	IN−	Inverting input - forms precision feedback path; input capacitance (17.9 pF diff) affects phase margin in high-Z applications.
EPAD	Exposed Thermal Pad	No internal electrical connection - soldered to PCB ground plane for 1°C/W junction-to-case thermal resistance and safe HV isolation.

Key Features

Feature	Design Value
High-Voltage Precision Architecture	Enables ±108.5 V output swing with 1 mV max VOS and 2 µV/°C drift - maintains sub-ppm linearity in HV DAC output stages across temperature.
Resistor-Adjustable Quiescent Current	0.6–3.3 mA range via RADJ pin - permits dynamic power scaling for portable ATE or continuous-duty LiDAR bias supplies without hardware change.
Integrated Temperature Monitor	Analog TMP output (1.9 V @ 25°C, −4.5 mV/°C) - eliminates need for external sensors in space-constrained HV modules requiring thermal derating.
IEC 61010-1 Compliant Packaging	7 mm × 7 mm LFCSP with EPAD - meets international safety spacing for 220 V working voltage, enabling certified industrial and medical HV designs.
Asymmetrical Supply Operation	Supports VCC-to-GND up to 175 V and VEE-to-GND down to −175 V - simplifies single-ended HV system design (e.g., +105 V/−105 V → 210 V span).

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage precision amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LT6015IMS8#PBF	Max supply 105 V; 1.5 µV/°C VOS drift; no TMP or RADJ; SO-8 package.	Limited to lower-voltage industrial sensors; lacks thermal monitoring and quiescent current tuning.	Choose for cost-sensitive, <100 V applications where integrated features are unnecessary.
OPA454AIDDA	Max supply 100 V; 10 V/µs slew rate; 100 mA output; no shutdown or TMP; 8-pin SO PowerPAD.	Better for high-current linear regulators; insufficient slew and voltage range for LiDAR/APD biasing.	Prefer when driving heavy resistive loads (>50 mA) at ≤100 V, not precision HV signal conditioning.

Compared with LT6015IMS8#PBF and OPA454AIDDA, the ADHV4702-1BCPZ-R7 uniquely combines 220 V capability, 74 V/µs slew, integrated TMP/SD/RADJ, and IEC-compliant packaging - making it the only option for precision, thermally aware, field-deployable HV analog front-ends above 100 V.

FAQ

What is the maximum safe supply voltage for ADHV4702-1BCPZ-R7?

The ADHV4702-1BCPZ-R7 has an absolute maximum VCC-to-VEE rating of 225 V, with recommended operation up to 220 V total span. VCC-to-GND must not exceed +180 V and VEE-to-GND must not go below −180 V. Exceeding these limits risks permanent damage. Always observe derating guidelines in the datasheet's Absolute Maximum Ratings table.

Does ADHV4702-1BCPZ-R7 require external compensation?

Yes - the ADHV4702-1BCPZ-R7 uses the COMP pin for external compensation to ensure stability across gains and load conditions. For unity-gain operation with resistive loads, a capacitor (typically 1–10 pF) from COMP to OUT is recommended. Driving capacitive loads or operating at higher gains requires tailored compensation per Figure 27 and the Applications Information section.

How is the temperature monitor (TMP) pin used in ADHV4702-1BCPZ-R7?

The TMP pin on ADHV4702-1BCPZ-R7 provides an analog voltage proportional to die temperature: 1.9 V at 25°C with −4.5 mV/°C drift. It is intended for monitoring thermal behavior and implementing overtemperature shutdown via external comparator circuitry - not for calibration. No load should be applied to TMP beyond a high-impedance ADC input.

Can ADHV4702-1BCPZ-R7 operate from a single supply?

Yes - the ADHV4702-1BCPZ-R7 supports single-supply operation up to 175 V (VCC to GND), with VEE tied to GND. Input common-mode range extends to within 3 V of GND, and output can swing to within ~1.5 V of GND under load. DGND must still be connected to 0 V AGND, and the EPAD grounded per IEC 61010-1 requirements.

What is the purpose of the RADJ pin on ADHV4702-1BCPZ-R7?

The RADJ pin on ADHV4702-1BCPZ-R7 allows resistor-based adjustment of quiescent current from 0.6 mA to 3.3 mA. Connecting RADJ to DGND via a resistor (0 Ω to 100 kΩ) sets IQ - enabling thermal/power trade-offs: lower IQ reduces self-heating in sealed enclosures, while higher IQ improves slew rate and bandwidth in high-speed applications.
