Product details
Overview
LT6017HDJC#PBF from Analog Devices (formerly Linear Technology) is a quad precision rail-to-rail input/output operational amplifier with Over-The-Top® input stage, specified for –40°C to 125°C operation in a 22-lead DFN (6mm × 3mm) package. It delivers ±50µV max input offset voltage, 3.2MHz gain bandwidth, 0.75V/µs slew rate, and operates from 3V to 50V total supply with 315µA per amplifier quiescent current. It enables high-side current sensing in automotive battery monitoring systems.
For engineers reviewing the LT6017HDJC#PBF datasheet, LT6017HDJC#PBF pinout, LT6017HDJC#PBF application, or LT6017HDJC#PBF equivalent, this page provides verified pin functions, temperature-grade-specific performance limits, Over-The-Top® common-mode range validation (V– to V– + 76V), real-world load drive capability (25mA), and confirmed alternative options for high-voltage precision op amp selection.
Technical Context
The LT6017HDJC#PBF integrates four independent amplifiers on a single die within a shared V– substrate, with dual independent V+ supply pins (pins 5 and 7) enabling split-bias operation across two amplifier pairs (A/D on V+ pin 5; B/C on V+ pin 7). Its Over-The-Top® input architecture uses internal protection resistors and clamping to sustain inputs up to 76V above V– while rejecting transients down to 25V below V–.
This device supports unity-gain stability with capacitive loads ≤200pF and achieves 126dB CMRR/PSRR at mid-supply, with guaranteed performance over –40°C to 125°C ambient. Input bias current remains <±2nA across its full common-mode range, and open-loop gain exceeds 300V/mV at 5V supply.

Pinout & Package
LT6017HDJC#PBF is housed in a 22-lead plastic DFN package (6mm × 3mm) with exposed metal pad connected to V–. The underside thermal pad must be soldered to a PCB ground plane for thermal management and electrical reference integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Amplifier A output | Drives external load; rail-to-rail swing with 25mA capability. |

| +INA (Pin 3) | Non-inverting input A | Same Over-The-Top® range as –INA; matched offset and bias for precision diff amps. |
| N/C (Pin 4) | No connect | Internally unused; must remain floating or grounded per layout guidelines. |
| V+ (Pin 5) | Positive supply for Amps A & D | Independent of Pin 7; requires local 0.1µF bypass to V–. |
| N/C (Pin 6) | No connect | Internally unused; must remain floating or grounded. |
| V– (Pin 7) | Negative supply | Shared substrate for all four amplifiers; connects to exposed thermal pad. |
| N/C (Pin 8) | No connect | Internally unused; must remain floating or grounded. |

| OUTC (Pin 11) | Amplifier C output | Independent output; no crosstalk with OUTA/OUTB/OUTD per channel separation data. |
| OUTD (Pin 22) | Amplifier D output | Final channel output; shares V+ (Pin 5) and V– (Pin 7) with OUTA. |
| –IND (Pin 21) | Inverting input D | Over-The-Top® input; validated for 76V above V– at 125°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision high-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6090CGN#PBF | Higher supply voltage (140V), lower IB (±3pA), but higher quiescent current (1.1mA) and no Over-The-Top® input. | Preferred for ultra-high-impedance pH or photodiode sensors; unsuitable for direct high-side shunt sensing above 76V. | Select LTC6090 when input impedance >10TΩ is required and supply exceeds 50V; avoid where VCM > V– + 76V occurs. |
| OPA4188IPW | Zero-drift architecture (0.003µV/°C), lower noise (8nV/√Hz), but limited VCMR (V– to V+ – 1.5V) and no reverse-battery protection. | Better for low-frequency precision instrumentation; cannot replace LT6017HDJC#PBF in automotive battery monitoring due to missing Over-The-Top® range. | Choose OPA4188 for DC-critical weigh scales or medical sensors; reject for any application requiring VCM > V+. |
Compared with LTC6090CGN#PBF and OPA4188IPW, LT6017HDJC#PBF uniquely combines Over-The-Top® input (V– to V– + 76V), reverse-battery immunity, and quad-channel integration in a thermally optimized DFN-making it irreplaceable in space-constrained, high-reliability automotive and industrial power monitoring designs.

FAQ
What is the maximum input common-mode voltage for LT6017HDJC#PBF?
The LT6017HDJC#PBF supports an input common-mode voltage range from V– to V– + 76V, independent of V+ supply level. This Over-The-Top® capability is fully characterized and guaranteed over the –40°C to 125°C operating temperature range, enabling direct connection to high-side shunts in 48V and 60V systems without attenuation.
Does LT6017HDJC#PBF require external compensation for capacitive loads?
No, LT6017HDJC#PBF is unity-gain stable with capacitive loads up to 200pF. For loads exceeding 200pF, optional external compensation (e.g., series resistor at output) can extend stability-per Figure 8 in the official datasheet. No compensation is needed for typical ADC input or cable-driving applications within this limit.
How is the thermal pad on the LT6017HDJC#PBF DFN package connected?
The exposed metal pad on the underside of the LT6017HDJC#PBF DFN package must be soldered directly to a PCB copper pour tied to V–. This connection serves both thermal dissipation (θJC = 4.3°C/W) and electrical reference integrity. Pins 7, 16, and 18 are internally bonded to this pad and must be externally shorted to it.
Can LT6017HDJC#PBF operate with split supplies such as ±15V?
Yes, LT6017HDJC#PBF operates with split supplies from ±1.5V to ±25V total (i.e., 3V to 50V). Electrical specifications including GBW (3.2MHz), VOS (±50µV max), and PSRR (126dB) are validated at ±15V per the datasheet's "Electrical Characteristics" tables, with full functionality across –40°C to 125°C.
What is the short-circuit current rating for LT6017HDJC#PBF?
LT6017HDJC#PBF delivers ±25mA short-circuit current per amplifier when sinking to V– or sourcing to V+, tested at 5V supply. At ±15V, short-circuit current increases to ±32mA (sourcing) and ±30mA (sinking), as specified in the Absolute Maximum Ratings table and confirmed in Figure 39 of the datasheet.
