Product details
Overview
TLV2369IDGKR from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for ultra-low-power sensor signal conditioning in battery-powered medical and portable electronics. It delivers 800 nA typical quiescent current per channel, 400 µV typical input offset voltage, and zero-crossover distortion across the full 1.8-V to 5.5-V supply range - enabling accurate amplification of microvolt-level signals in blood glucose meters and wearable health monitors.
For engineers reviewing the TLV2369IDGKR datasheet, TLV2369IDGKR pinout, TLV2369IDGKR application, or TLV2369IDGKR equivalent, this page provides verified specifications, VSSOP-8 package layout guidance, dual-channel precision amplifier use cases, and validated alternative options for nanopower analog front-end design.
Technical Context
The TLV2369IDGKR implements a zero-crossover distortion input stage that eliminates the common-mode transition error found in conventional complementary-input op amps, ensuring consistent linearity from V– to V+ rails. Its 12-kHz gain-bandwidth product and 0.005 V/µs slew rate support stable DC-coupled amplification and low-frequency filtering without phase inversion artifacts.
This dual op amp operates with true rail-to-rail input and output swing (25 mV from rails at 10-kΩ load), supports –40°C to +125°C extended temperature operation, and maintains 80 dB minimum PSRR and CMRR over its full common-mode range - critical for high-accuracy measurements in noisy, single-supply embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V - enables direct interface with Li-ion, coin-cell, and 3.3-V logic supplies without regulation. |
| Quiescent Current | 800 nA/ch (typ) - extends battery life in always-on monitoring circuits beyond 10 years on a CR2032 cell. |
| Input Offset Voltage | 400 µV (typ), 2 mV (max) - supports sub-millivolt signal resolution in precision transducer interfaces. |
| Offset Drift | 0.5 µV/°C (typ) - minimizes thermal-induced baseline shift in uncalibrated portable diagnostics. |
| Gain-Bandwidth Product | 12 kHz - sufficient for anti-aliasing, sensor excitation, and DC-stable gain stages up to G = 100. |
| Common-Mode Range | V– to V+ - allows direct sensing of ground-referenced biopotentials without level-shifting circuitry. |
| Output Swing | 25 mV from rail (RL = 10 kΩ) - preserves dynamic range in 1.8-V ADC reference designs. |
Pinout & Package
TLV2369IDGKR is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with 0.65-mm lead pitch, optimized for space-constrained PCB layouts in handheld medical devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Output, Channel A | Amplified signal source for first analog channel; drives ADC inputs or low-power comparators directly. |
| 2 - IN– A | Inverting Input, Channel A | Accepts feedback network for inverting configurations; requires guard ring in high-impedance pH or ECG sensing. |
| 3 - IN+ A | Noninverting Input, Channel A | High-impedance (10¹³ Ω || 6 pF) node for direct connection to thermistor, strain gauge, or electrode interfaces. |
| 4 - V– | Negative Supply / Ground | Reference return for single-supply operation; must be low-impedance to avoid PSRR degradation. |
| 5 - IN+ B | Noninverting Input, Channel B | Independent second channel input; enables differential pair or dual-sensor readout without external multiplexing. |
| 6 - IN– B | Inverting Input, Channel B | Supports independent gain-setting resistors per channel; avoids crosstalk in multi-parameter biosensors. |
| 7 - OUT B | Output, Channel B | Second analog output; usable for ratiometric reference generation or active filtering in dual-path architectures. |
| 8 - V+ | Positive Supply | Accepts 1.8–5.5 V; bypassed with 0.1-µF ceramic capacitor placed ≤2 mm from pin to suppress supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|

| Rail-to-Rail I/O | Enables full utilization of 1.8-V ADC input range without level-shifting, reducing component count and power in portable diagnostics. |
| 800-nA Quiescent Current | Permits continuous sensor biasing and signal conditioning in energy-harvesting or coin-cell-powered wearables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual nanopower operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV821DRX | Lower 650 nA IQ but only 3.5 kHz GBW; no zero-crossover architecture - exhibits crossover distortion near rails. | Suitable for DC-coupled sensor buffers where bandwidth <5 kHz suffices and rail-linearity is noncritical. | Choose LPV821DRX when ultra-low IQ dominates over linearity requirements and system bandwidth is ≤3 kHz. |
| OPA316IDBVR | Higher 100 µA IQ but 10 MHz GBW and 1.5 mV max VOS; includes shutdown mode not present in TLV2369IDGKR. | Better for higher-speed analog front-ends requiring AC coupling or active filtering above 100 kHz. | Choose OPA316IDBVR when system demands >100 kHz bandwidth or integrated power-down control for intermittent sensing. |
Compared with LPV821DRX and OPA316IDBVR, TLV2369IDGKR uniquely balances sub-1-µA power, rail-to-rail linearity, and 12-kHz bandwidth - making it the only option among the three qualified for precision DC-coupled biosensing where zero-crossover distortion is mandatory.

FAQ
What is the maximum operating temperature range for TLV2369IDGKR?
The TLV2369IDGKR is specified for continuous operation from –40°C to +125°C, with electrical characteristics guaranteed over –40°C to +85°C. Its extended junction temperature rating of 150°C supports reliability in sealed enclosures or high-ambient environments such as automotive cabin modules or industrial motor controllers where thermal derating is required.
Does TLV2369IDGKR support true rail-to-rail input with 1.8-V supply?
Yes, TLV2369IDGKR supports true rail-to-rail input common-mode range from V– to V+ across its entire 1.8-V to 5.5-V supply range. This is enabled by its zero-crossover distortion input architecture, which eliminates the input offset discontinuity seen in standard CMOS or bipolar input op amps - confirmed in Figure 1 of the SBOS757 datasheet.
Can TLV2369IDGKR drive capacitive loads without oscillation?
TLV2369IDGKR can safely drive up to 20 pF capacitive loads without external compensation, as verified in Figure 10 of the SBOS757 datasheet. For loads exceeding 20 pF, a series resistor (≥100 Ω) between the output and capacitive node is recommended to maintain phase margin and prevent peaking or ringing in sensor buffering applications.
What is the input bias current specification for TLV2369IDGKR at 85°C?
The input bias current for TLV2369IDGKR remains ≤10 pA over the full –40°C to +85°C operating range, as specified in Section 6.6 of the SBOS757 datasheet. This ultra-low, temperature-stable bias current is critical for interfacing with high-impedance sources such as pH electrodes or photodiode transimpedance networks without introducing significant offset error.
Is TLV2369IDGKR pin-compatible with other dual op amps in VSSOP-8?
No, TLV2369IDGKR is not pin-compatible with standard dual op amps such as LMV358 or MCP6022 in VSSOP-8. Its pinout follows TI's TLVx369 family assignment (OUT A, IN– A, IN+ A, V–, IN+ B, IN– B, OUT B, V+), differing from industry-standard dual op amp pinouts - requiring PCB layout revision for substitution.
