Product details
Overview
LT6017IDJC#PBF from Analog Devices (formerly Linear Technology) is a quad precision rail-to-rail input/output operational amplifier featuring Over-The-Top® input stage, ±50µV max input offset voltage, 3.2MHz gain bandwidth, 0.75V/µs slew rate, and operation from 3V to 50V total supply. It enables high-side current sensing and battery monitoring in automotive and industrial power systems.
For engineers reviewing the LT6017IDJC#PBF datasheet, LT6017IDJC#PBF pinout, LT6017IDJC#PBF application, or LT6017IDJC#PBF equivalent, key selection criteria include its 76V input common-mode range above V–, –40°C to 85°C temperature grade, 22-pin DFN package with exposed V– pad, and reverse-battery protection to 50V.
Technical Context
The LT6017IDJC#PBF integrates two dual-amplifier dice in one 22-lead DFN package, sharing a common V– substrate but supporting independent V+ supplies on pins 5 (A/D channels) and 7 (B/C channels). Its Over-The-Top input stage allows inputs to operate up to 76V above V– regardless of V+ level, with internal resistors protecting against transients down to 25V below V–.
Each amplifier draws only 315µA quiescent current, achieves 126dB CMRR and PSRR, supports unity-gain stability with ≥200pF capacitive loads, and delivers rail-to-rail output swing into 5mA loads - enabling direct interfacing with ADCs and microcontrollers without level-shifting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6090CGN#PBF | Single-channel, higher supply voltage (140V), lower input bias current (±3pA), but no Over-The-Top input stage. | Requires external level-shifting for >V+ inputs; suited for ultra-high-impedance sensor interfaces rather than high-side sensing. | Select when input voltage stays within supply rails and femtoampere bias current is critical. |
| OPA4188IPW | Quad zero-drift op amp, 0.003µV/°C offset drift, but limited common-mode range (V– to V+ – 1.5V) and no reverse-battery protection. | Cannot perform high-side sensing above V+; best for precision low-voltage instrumentation where rail constraints dominate. | Select when ultra-low drift dominates requirements and input voltage remains strictly within supply rails. |
Compared with LTC6090CGN#PBF and OPA4188IPW, the LT6017IDJC#PBF uniquely combines quad channel count, Over-The-Top input capability, reverse-battery protection, and industrial temperature range - making it the only option for compact, robust high-voltage monitoring in space-constrained automotive and industrial modules.

FAQ
What is the maximum input voltage relative to V– for LT6017IDJC#PBF?
The LT6017IDJC#PBF supports an input common-mode voltage range from V– to V– + 76V. This Over-The-Top® capability allows direct connection to high-side nodes in 48V or 60V systems without attenuation or level-shifting circuitry. The specification is guaranteed over the full –40°C to 85°C operating temperature range and applies independently of the V+ supply voltage.
Does LT6017IDJC#PBF require external compensation for capacitive loads?
No, the LT6017IDJC#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 drive capability. The device's robust phase margin (>35° at 200pF) ensures stable operation in typical sensor buffering and ADC driving applications without added components.
How is the exposed pad on the LT6017IDJC#PBF DFN package connected?
The exposed metal pad on the LT6017IDJC#PBF must be soldered to the PCB's V– net and thermal ground plane. Pins 7 and 16 are dedicated V– connections that must be tied together and to this pad. Proper thermal connection reduces junction temperature rise by >40°C under full load and ensures specified electrical performance, especially short-circuit current and output swing.
Can LT6017IDJC#PBF operate with independent V+ supplies for different amplifier sections?
Yes - the LT6017IDJC#PBF supports independent V+ supplies: pins 5 powers amplifiers A and D, while pin 7 powers amplifiers B and C. Each V+ pin requires its own 0.1µF bypass capacitor to V–. This architecture enables monitoring of multiple isolated power domains (e.g., 12V and 48V rails) within a single IC, reducing system-level component count and board area.
What is the reverse battery protection rating for LT6017IDJC#PBF?
The LT6017IDJC#PBF is protected against reverse battery conditions up to –50V, drawing less than 5µA supply current during fault. This meets ISO 16750-2 automotive requirements for jump-start and polarity reversal events. Protection is inherent to the input stage design and requires no external diodes or FETs - preserving signal integrity and minimizing BOM cost.
