Product details
Overview
LT6001CMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual precision rail-to-rail input/output operational amplifier optimized for micropower, low-voltage operation. It delivers 13–16 µA supply current per amplifier, 600 µV max input offset voltage, and full rail-to-rail swing on supplies as low as 1.8 V. It is used in battery-powered gas sensing front-ends where ultra-low quiescent current and precision DC accuracy at sub-2V operation are critical.
For engineers reviewing the LT6001CMS8#TRPBF datasheet, LT6001CMS8#TRPBF pinout, LT6001CMS8#TRPBF application, or LT6001CMS8#TRPBF equivalent, key selection criteria include guaranteed 1.8V operation, shutdown capability (in DD variant only), MS8 package thermal performance (θJA = 250°C/W), and verified rail-to-rail behavior across –40°C to 85°C.
Technical Context
The LT6001CMS8#TRPBF employs a complementary PNP/NPN input stage enabling true rail-to-rail common-mode input range (0 V to VS) and output swing within 30 mV of both rails. Its folded-cascode second stage and complementary drive generator maintain stability and precision under light capacitive loads up to 100 pF.
It operates with no internal shutdown function - unlike the 10-lead LT6001DD variant - and draws 13–24 µA per amplifier across temperature. Input bias current polarity reverses with common-mode voltage due to dual-input-stage architecture, requiring matched source impedances to minimize offset error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 16 V - enables direct use with single-cell Li-ion (3.0–4.2 V), NiMH (1.2 V × 2), or 1.8 V logic rails without level-shifting. |
| Quiescent Current per Amp | 13 µA (typ), 16 µA (max) at 25°C - supports >1-year battery life in always-on portable instrumentation with dual-channel signal conditioning. |
| Input Offset Voltage | 600 µV (max) over –40°C to 85°C - ensures ≤0.012% gain error in 50 mV oxygen sensor outputs without trimming. |
| Input/Output Range | Rail-to-rail input (0 V to VS) and output (within 30 mV of V+/V–) - eliminates need for external biasing in single-supply transducer interfaces. |
| Gain Bandwidth Product | 32 kHz (min) at 1.8 V - sufficient for DC–10 Hz gas sensor amplification and active filtering without compromising power budget. |
| Operating Temperature | –40°C to 85°C industrial grade - qualified for deployment in outdoor environmental monitoring enclosures. |
| Package | 8-lead MSOP (MS8) - 3 mm × 3 mm footprint with exposed pad tied to V–, supporting thermal dissipation in space-constrained PCBs. |
Pinout & Package
LT6001CMS8#TRPBF is housed in an 8-lead plastic MSOP (MS8) package with exposed thermal pad connected to V–. The package has θJA = 250°C/W and is RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; sinks/source up to 4 mA at 1.8 V; requires no pull-up for high-Z shutdown (not supported in MS8). |
| 2 (IN– A) | Inverting input A | Accepts differential input down to V–; includes 30 kΩ series protection resistor; bias current flows out below ~1 V CM, in above. |
| 3 (IN+ A) | Non-inverting input A | Same protection and bias behavior as IN– A; matched impedance required to cancel IB-induced offset. |
| 4 (V–) | Negative supply / ground reference | Reference node for both amplifiers; exposed pad internally bonded to this pin; must be low-impedance for noise immunity. |
| 5 (V+) | Positive supply | Accepts 1.8–16 V; requires local 0.01 µF ceramic bypass within 25 mm; additional 4.7 µF recommended for dynamic loads. |
| 6 (OUT B) | Amplifier B output | Independent rail-to-rail output; identical specs to OUT A; usable for dual-sensor or gain-stage cascading. |
| 7 (IN– B) | Inverting input B | Electrically isolated from IN– A; same ESD and phase-reversal protection; supports independent feedback networks. |
| 8 (IN+ B) | Non-inverting input B | Matches IN+ A characteristics; enables simultaneous dual-channel low-power signal acquisition. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V minimum supply | Enables direct interface with energy-harvesting circuits and single alkaline/NiMH cells without boost converters. |
| Rail-to-rail I/O | Maximizes dynamic range in 1.8–3.3 V systems; eliminates DC biasing components and associated drift errors. |
| 600 µV max VOS | Guaranteed over full temperature range - reduces calibration burden in portable medical and environmental sensors. |
| 13 µA quiescent current | Per amplifier at 1.8 V - allows dual-opamp front-end to consume <30 µA total, extending coin-cell life beyond 5 years. |
| Phase reversal protection | Prevents output inversion when inputs are driven 2 V below V–, critical for unregulated battery-fed sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX44260ASA+ | Single-channel, 900 nA IQ, 10 µV VOS, no rail-to-rail output (VOH = VCC – 0.8 V) | Lower power but incompatible rail-to-rail output; requires higher supply or level-shifting for 1.8 V ADC interfacing. | Select only if ultra-low IQ dominates and output swing margin >800 mV is acceptable. |
| OPA316IDBVR | Dual-channel, 400 µA IQ, 250 µV VOS, rail-to-rail I/O, 10 MHz GBW | 10× higher supply current; wider bandwidth unnecessary for DC/low-frequency sensor signals. | Choose only if system requires >100 kHz signal bandwidth and can absorb 8× higher quiescent power. |
Compared with MAX44260ASA+ and OPA316IDBVR, the LT6001CMS8#TRPBF uniquely balances sub-16 µA quiescent current, guaranteed 1.8 V operation, rail-to-rail I/O, and 600 µV VOS in an industry-standard MS8 package - making it optimal for long-life, single-supply, precision analog front-ends.

FAQ
Does LT6001CMS8#TRPBF support shutdown mode?
No, the LT6001CMS8#TRPBF does not include a shutdown pin. Shutdown functionality is only available in the 10-lead LT6001DD DFN variant. The MS8 package (LT6001CMS8#TRPBF) has fixed operation and draws 13–24 µA per amplifier continuously across temperature. To achieve ultra-low standby current, external enable circuitry or power gating must be implemented.
What is the maximum capacitive load LT6001CMS8#TRPBF can drive stably?
The LT6001CMS8#TRPBF is characterized to drive up to 100 pF capacitive load with minimal overshoot (<10%) in unity-gain configuration. For loads exceeding 100 pF, a series isolation resistor (≥100 Ω) between output and capacitance is recommended to maintain phase margin above 45°, as confirmed in Figure 23 of the datasheet.
Is LT6001CMS8#TRPBF specified for operation at 1.8 V across the full temperature range?
Yes, the LT6001CMS8#TRPBF is fully specified and guaranteed over –40°C to 85°C at 1.8 V supply, including input offset voltage (≤600 µV), supply current (≤24 µA), and rail-to-rail output swing (≤30 mV from rails). This is explicitly stated in the "Fully Specified on 1.8V and 5V Supplies" feature list and electrical characteristics tables.
How does input bias current behave across common-mode voltage in LT6001CMS8#TRPBF?
The LT6001CMS8#TRPBF uses dual-input PNP/NPN stages, causing input bias current polarity to reverse near mid-supply. Below ~1 V CM, bias current flows *out* of inputs (–2 to –6 nA); above ~1 V CM, it flows *in* (+4 to +12 nA). To minimize offset, keep source impedances equal on IN+ and IN– pins - a design requirement confirmed in the Applications Information section.
Can LT6001CMS8#TRPBF be used with split supplies?
Yes, the LT6001CMS8#TRPBF supports split supplies (e.g., ±2.5 V) with full rail-to-rail input and output operation. The absolute maximum total supply voltage is 18 V, and PSRR exceeds 86 dB across 1.8–16 V. When using split supplies, both V+ and V– pins require local 0.01 µF bypass capacitors, as specified in the Application Information section.
