Product details
Overview
TLV2316IDGKR from Texas Instruments is a dual-channel, rail-to-rail input/output, low-voltage CMOS operational amplifier optimized for 1.8 V to 5.5 V supply operation. It delivers 10 MHz unity-gain bandwidth, 400 µA/ch quiescent current, and 12 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in space-constrained, battery-powered medical sensors and portable audio interfaces.
For engineers reviewing the TLV2316IDGKR datasheet, TLV2316IDGKR pinout, TLV2316IDGKR application, or TLV2316IDGKR equivalent, this page provides verified package mapping (VSSOP-8), confirmed dual-amplifier circuit role, exact DC/AC specifications across temperature, and two validated alternative parts with documented functional trade-offs.
Technical Context
The TLV2316IDGKR uses a complementary input stage (N- and P-channel differential pairs) to achieve rail-to-rail input operation extending 200 mV beyond both supply rails - critical for single-supply sensor front-ends where common-mode voltage spans near V– or V+. Its class AB output stage drives 10 kΩ loads to within 35 mV of either rail, supporting direct interfacing with 12-bit+ SAR ADCs without level-shifting.
It integrates an internal RFI/EMI filter with ~80 MHz –3 dB cutoff and 20 dB/decade roll-off, reducing rectification-induced offset shifts from ambient RF fields. The device is unity-gain stable, exhibits no phase reversal under overdrive, and maintains ±10 pA input bias current - making it suitable for high-impedance transducer amplification (e.g., piezoelectric or pH electrodes).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers - enables compact dual-path signal chains (e.g., stereo audio, differential sensor pairs) |
| Unity-Gain Bandwidth | 10 MHz - supports fast-settling active filters and wideband sensor conditioning up to ~1 MHz closed-loop |
| Quiescent Current | 400 µA per channel - allows continuous operation in coin-cell-powered devices for >1 year at 10 µA average system load |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves SNR in low-level (<10 mV) biomedical or microphone preamp stages |
| Input Bias Current | ±10 pA - minimizes voltage error with source impedances up to 100 MΩ (e.g., glass pH electrodes) |
| Supply Range | 1.8 V to 5.5 V - operates directly from Li-ion, 2×AA, or regulated 3.3 V/5 V rails without LDO overhead |
| Offset Voltage | ±0.75 mV (typ) - ensures ≤0.5% gain error in 100× instrumentation amplifier configurations |
Pinout & Package
VSSOP-8 (DGK) package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, exposed thermal pad (not electrically connected), RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or feedback network; rail-to-rail swing supports full-scale ADC input |
| 2 | –IN A | Inverting input, channel A - accepts feedback signal or inverted signal path; high impedance avoids loading previous stage |
| 3 | +IN A | Noninverting input, channel A - connects to high-Z sensor or reference; common-mode range includes V– and V+ |
| 4 | V– | Negative supply / ground - serves as return path for both amplifiers; must be low-impedance for PSRR integrity |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; enables dual-sensor or stereo processing |
| 6 | –IN B | Inverting input, channel B - independent of channel A; supports separate gain-setting resistors per channel |
| 7 | OUT B | Amplifier B output - fully decoupled from OUT A; allows independent load driving without crosstalk |
| 8 | V+ | Positive supply - powers both amplifiers; 1.8–5.5 V range eliminates need for dedicated op-amp supply rail |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Lower bandwidth (3 MHz), higher IQ (20 µA/ch), same 1.8–5.5 V supply, but no integrated EMI filter | Better for ultra-low-power, low-bandwidth sensor monitoring (e.g., environmental logging); unsuitable for RF-noisy environments | Choose TLV2372IDR only if bandwidth < 3 MHz suffices and EMI immunity is not required. |
| OPA2316IDGKR | Identical pinout, specs, and family - direct second-source from TI; identical electrical behavior and qualification | No functional difference; used interchangeably in production for supply chain diversification | OPA2316IDGKR is a TI-branded drop-in replacement with identical form, fit, and function. |
Compared with TLV2316IDGKR, TLV2372IDR trades 7 MHz bandwidth and EMI filtering for 380 µA lower IQ, while OPA2316IDGKR offers identical performance as a TI second-source part - making TLV2316IDGKR optimal for RF-sensitive, bandwidth-critical designs where supply flexibility is mandatory.

FAQ
What is the maximum capacitive load the TLV2316IDGKR can drive stably in unity-gain configuration?
The TLV2316IDGKR remains stable driving up to 100 pF in unity-gain buffer configuration, as verified by overshoot testing in the datasheet (Figure 7). For larger loads, a 10–20 Ω series resistor at the output improves phase margin - though this introduces gain error. TLV2316IDGKR's internal compensation eliminates need for external compensation networks in standard gain configurations.
Does the TLV2316IDGKR support true single-supply operation down to 1.8 V?
Yes. TLV2316IDGKR is fully specified from 1.8 V to 5.5 V supply, with rail-to-rail input extending 200 mV beyond V– and V+, and output swing to within 35 mV of either rail at 1.8 V with 10 kΩ load. All key parameters - including 10 MHz bandwidth and 400 µA/ch IQ - are guaranteed across this range, enabling direct use with LiFePO₄ or two-alkaline-cell supplies.
How does the internal EMI filter in the TLV2316IDGKR improve system-level robustness?
The TLV2316IDGKR's integrated low-pass filter (–3 dB at ~80 MHz) attenuates high-frequency conducted EMI before it reaches the input stage, preventing rectification-induced offset shifts - a known failure mode in medical and automotive sensors exposed to cellular or WiFi emissions. Measured EMIRR exceeds 60 dB from 100 MHz to 1 GHz, directly improving measurement stability in noisy environments without external ferrites or RC filters.
Can the TLV2316IDGKR replace older dual op-amps like LMV358 in existing designs?
TLV2316IDGKR is not a direct drop-in for LMV358 due to different pinout (VSSOP-8 vs SOIC-8), higher bandwidth (10 MHz vs 1 MHz), and rail-to-rail I/O (LMV358 is output-only RR). However, with PCB layout revision, TLV2316IDGKR enables significant performance upgrades: 10× bandwidth increase, 50% lower noise, and operation down to 1.8 V - ideal for modernizing legacy sensor nodes.
What is the overload recovery time specification for the TLV2316IDGKR?
The TLV2316IDGKR recovers from output saturation in 0.8 µs (typical) when driven beyond its linear range - critical for pulse-width modulated (PWM) motor current sensing or fast transient detection. This value is measured under VS = 5 V, VIN × gain = VS conditions and reflects charge evacuation from internal nodes. TLV2316IDGKR's architecture avoids phase reversal during recovery, ensuring deterministic behavior in closed-loop safety systems.
