Product details
Overview
ADA4099-2HCPZ from Analog Devices is a dual-channel, precision, Over-The-Top™ operational amplifier designed for high-voltage, abusive-environment signal conditioning. It operates from +3.15 V to +50 V (single supply) or ±25 V (split), delivers 8 MHz gain bandwidth, 5.5 V/µs slew rate, and maintains ±40 µV max input offset voltage across −55°C to +150°C. It is used in battery monitoring, industrial current sensing, and 4 mA–20 mA transmitter front ends.
For engineers reviewing the ADA4099-2HCPZ datasheet, ADA4099-2HCPZ pinout, ADA4099-2HCPZ application, or ADA4099-2HCPZ equivalent, key selection criteria include its rail-to-rail I/O, −VS − 0.1 V to −VS + 70 V common-mode range, 1.5 mA/channel quiescent current, ±2 kV HBM ESD rating, and H-grade temperature support up to +150°C.
Technical Context
The ADA4099-2HCPZ implements a robust Over-The-Top™ input stage enabling operation with inputs up to 70 V above the negative rail-critical for high-side current sensing and supply monitoring where input voltages exceed the positive supply. Its voltage-feedback architecture ensures unity-gain stability and drives capacitive loads up to 100 pF.
Each channel features independent shutdown control (SHDN1/SHDN2), low 20 µA max shutdown current, and input overvoltage tolerance up to ±80 V differential without phase reversal or accuracy degradation. The device's 118 dB minimum CMRR and 123 dB PSRR maintain precision under noisy, high-common-mode conditions typical in industrial power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +3.15 V to +50 V single or ±25 V split - supports wide industrial and automotive battery monitoring rails. |
| Gain Bandwidth Product | 8 MHz typical - enables stable closed-loop operation at gains ≥1 with bandwidth >100 kHz for fast sensor signals. |
| Slew Rate | 5.5 V/µs typical at ΔVOUT = 25 V - supports full-scale step response in <2 µs for transient-critical applications. |
| Input Offset Voltage | ±40 µV maximum - ensures sub-0.1% error in mV-level sensor outputs (e.g., shunt-based current sense). |
| Common-Mode Input Range | −VS − 0.1 V to −VS + 70 V - allows direct high-side sensing of 48 V/60 V bus voltages without level-shifting. |
| Quiescent Current/Channel | 1.5 mA typical - balances performance and power efficiency in always-on industrial monitors. |
| Operating Temperature | −55°C to +150°C (H grade) - qualified for under-hood, motor control, and downhole equipment. |
Pinout & Package
The ADA4099-2HCPZ is housed in a 10-lead LFCSP (Lead Frame Chip Scale Package) with exposed pad, optimized for thermal dissipation in high-power-density industrial PCBs. Pin 1 is VOUT1; Pin 10 is +VS; EPAD must be connected to −VS for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | Output of Channel 1 - rail-to-rail capable, drives up to 20 mA, high-impedance in shutdown. |
| 2 | −IN1 | Inverting input of Channel 1 - part of Over-The-Top™ input stage tolerant to ±80 V differential stress. |
| 3 | +IN1 | Noninverting input of Channel 1 - supports common-mode voltages up to −VS + 70 V without damage. |
| 4 | −VS | Negative supply rail - reference for all inputs/outputs; EPAD must connect here for thermal integrity. |
| 5 | SHDN1 | Shutdown control for Channel 1 - active-high logic (>−VS + 1.5 V); enables per-channel power gating. |
| 6 | SHDN2 | Shutdown control for Channel 2 - independent of SHDN1, allowing asymmetric channel enablement. |
| 7 | +IN2 | Inverting input of Channel 2 - note: pin function differs from SOIC/MSOP variants (no cross-pin compatibility). |
| 8 | −IN2 | Noninverting input of Channel 2 - inverted labeling vs. standard convention; verified per Table 8. |
| 9 | VOUT2 | Output of Channel 2 - identical drive capability and shutdown behavior as VOUT1. |
| 10 | +VS | Positive supply rail - requires ≥0.1 µF local bypass to −VS for high-frequency PSRR maintenance. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top™ Input Stage | Enables direct sensing of signals 70 V above −VS - eliminates external level shifters in high-side current monitors. |
| ±80 V Differential Input Tolerance | Prevents latch-up or parametric shift during load dump or inductive kick events in automotive/industrial systems. |
| 1.5 mA/Channel Quiescent Current | Supports continuous operation in battery-backed systems while maintaining 8 MHz bandwidth and low noise. |
| ±2 kV HBM / ±1.25 kV FICDM ESD Rating | Reduces need for external protection in field-deployed equipment subject to handling and system-level transients. |
| −55°C to +150°C Operating Range | Validated for extended life in engine compartments, motor drives, and oil/gas electronics without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4177-2ARZ | Lower 1.8 nV/√Hz noise, but only −VS to +VS (not Over-The-Top™) input range; 5.5 MHz GBP; H-grade not available. | Not suitable for high-side sensing >+VS; better for low-noise, low-bandwidth sensor interfaces. | Select ADA4177-2ARZ when ultra-low noise dominates over common-mode range and temperature range. |
| LT6015IMS8#PBF | Wider −VS − 0.3 V to +VS + 76 V input range, but 1.3 MHz GBP, 0.4 V/µs slew rate, and 125°C max temp. | Acceptable for slower, higher-CMRR industrial monitors but cannot support fast 4–20 mA settling or wide-temp operation. | Select LT6015IMS8#PBF only if Over-The-Top™ range >70 V is mandatory and speed/temperature are secondary. |
Compared with ADA4177-2ARZ and LT6015IMS8#PBF, the ADA4099-2HCPZ uniquely combines 8 MHz bandwidth, −55°C to +150°C operation, and true Over-The-Top™ input capability - making it the sole option for high-speed, high-temperature, high-common-mode industrial signal chains.

FAQ
What is the maximum continuous supply voltage for ADA4099-2HCPZ?
The ADA4099-2HCPZ supports a maximum continuous supply voltage of +50 V (single supply) or ±25 V (dual supply), as defined by time-dependent dielectric breakdown limits. Transient overshoot up to +60 V is tolerated briefly, but dc operation must remain ≤50 V. This rating applies directly to the ADA4099-2HCPZ and is validated across its full −55°C to +150°C operating range.
Does ADA4099-2HCPZ support rail-to-rail input and output operation?
Yes, the ADA4099-2HCPZ provides true rail-to-rail input and output operation. Its Over-The-Top™ input stage extends the common-mode range to −VS − 0.1 V to −VS + 70 V, while the output swings within 45 mV of both rails under light load. This capability is fully specified and tested for the ADA4099-2HCPZ in its 10-lead LFCSP package.
What is the function of Pins 7 and 8 on ADA4099-2HCPZ?
On the ADA4099-2HCPZ (10-lead LFCSP), Pin 7 is +IN2 (inverting input of Channel 2) and Pin 8 is −IN2 (noninverting input of Channel 2). This reversed labeling versus conventional op amp pinouts is explicitly documented in Table 8 of the datasheet and is unique to the LFCSP variant - critical for correct PCB layout and schematic capture of the ADA4099-2HCPZ.
Can ADA4099-2HCPZ drive capacitive loads?
Yes, the ADA4099-2HCPZ is characterized to drive capacitive loads up to 100 pF while maintaining stability and specified settling time. This capability is confirmed in the datasheet's "General Description" and "Applications Information" sections and applies to the ADA4099-2HCPZ in all operating conditions, including over temperature and across supply voltages from 3.15 V to 50 V.
Is the exposed pad (EPAD) of ADA4099-2HCPZ electrically connected?
Yes, the EPAD of the ADA4099-2HCPZ is internally connected to the −VS power plane and must be soldered to a PCB copper area tied to −VS. This connection is mandatory for thermal performance, EMI suppression, and achieving specified PSRR and output drive capability - as stated in Table 8 and Figure 6 of the official datasheet for the ADA4099-2HCPZ.
