Product details
Overview
TLV2464CD from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power portable and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity buffering of ADC inputs in battery-powered sensor front-ends.
For engineers reviewing the TLV2464CD datasheet, TLV2464CD pinout, TLV2464CD application, or TLV2464CD equivalent, this page provides verified package mapping (SOIC-14), confirmed shutdown functionality per channel, rail-to-rail dynamic range at 2.7–6 V supply, and real-world design guidance for precision analog interfaces in automotive and industrial control systems.
Technical Context
The TLV2464CD implements a CMOS input stage with rail-to-rail input common-mode range extending beyond both supply rails (0 V to VDD), and an output stage capable of swinging within 100 mV of each rail under 10 mA load. Its 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate are achieved with only 500 µA per amplifier, making it suitable for AC-coupled sensor amplification and active filtering where power and headroom are constrained.
Each of the four amplifiers features independent shutdown control (pins 1/2SHDN and 3/4SHDN), reducing supply current to 0.3 µA per channel when asserted. The device operates across 0°C to 70°C (C-suffix) and supports single-supply (2.7–6 V) or split-supply (±1.35–±3 V) configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer operation up to ~6 MHz or closed-loop gain of 10 at ~640 kHz. |
| Slew Rate | 1.6 V/µs - supports clean 1 VPP signals up to ~250 kHz without slew-induced distortion. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.01% gain error in 1 V full-scale instrumentation amplifier stages. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, critical for always-on sensor nodes. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails at 10 mA - maximizes dynamic range in 3.3 V systems. |
| Output Drive | ±80 mA (min) - drives 37.5 Ω loads directly, eliminating need for external buffers in DAC output stages. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or bridge sensor amplification. |
Pinout & Package
TLV2464CD is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package (D suffix), 3.9 mm × 8.7 mm body, 1.27 mm pitch, RoHS-compliant, with standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - rail-to-rail capable, ±80 mA sink/source. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance CMOS node, 1300 pA bias current. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - rail-to-rail common-mode range (0 V to VDD). |
| 4 | GND | Analog ground reference - shared return for all four amplifiers and shutdown logic. |
| 5 | NC | No internal connection - unused pad; must be left floating or grounded per layout guidelines. |
| 6 | 1/2SHDN | Shutdown control for Amplifiers A & B - logic high (>2 V) enables; low (<0.7 V) disables (0.3 µA/ch). |
| 7 | VDD+ | Positive supply rail - accepts 2.7–6 V single supply or +VDD in split-supply mode. |
| 8 | 2OUT | Amplifier B output - electrically identical to Pin 1, fully independent. |
| 9 | 2IN− | Inverting input of Amplifier B - matched to Pin 2 in offset, noise, and bias characteristics. |
| 10 | 2IN+ | Non-inverting input of Amplifier B - rail-to-rail input stage, same as Pin 3. |
| 11 | 3IN+ | Non-inverting input of Amplifier C - third channel, identical electrical specs to Pins 3 & 10. |
| 12 | 3IN− | Inverting input of Amplifier C - matched to Pins 2 & 9. |
| 13 | 3OUT | Amplifier C output - third rail-to-rail output, same drive capability as Pins 1 & 8. |
| 14 | 3/4SHDN | Shutdown control for Amplifiers C & D - independent of Pin 6; enables selective channel disable. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464ID | Same electrical specs but rated for −40°C to 125°C industrial temperature range; higher max input offset (2000 µV). | Required for under-hood automotive or factory-floor PLC modules exposed to extended thermal stress. | Select TLV2464ID when ambient operating temperature exceeds 70°C or AEC-Q100 qualification is mandated. |
| OPA4340UA | Lower input offset (125 µV max), lower noise (8 nV/√Hz), but higher supply current (750 µA/ch); no shutdown function. | Better suited for ultra-low-error medical instrumentation where power is secondary to accuracy. | Choose OPA4340UA only if 100 µV offset margin is insufficient and shutdown is not required in the system architecture. |
Compared with TLV2464ID, TLV2464CD offers tighter offset and lower cost for commercial-temperature applications, while OPA4340UA trades power efficiency for enhanced DC precision and noise performance - making TLV2464CD optimal for cost-sensitive, battery-constrained designs needing flexible channel management.

FAQ
What is the operating temperature range for TLV2464CD?
The TLV2464CD is specified for commercial operation from 0°C to 70°C (C-suffix). This range is validated per TI's SLOS220J datasheet, with all key parameters - including input offset voltage, supply current, and gain-bandwidth product - guaranteed across this interval without derating. It is not qualified for extended industrial or automotive temperature ranges.
Does TLV2464CD support true rail-to-rail input and output?
Yes, TLV2464CD supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swings within 100 mV of both rails at 10 mA load). This is confirmed in the "Features" section and electrical characteristics tables of the SLOS220J datasheet, enabling full dynamic range utilization in 3.3 V and 5 V single-supply systems.
How does the shutdown feature work on TLV2464CD?
TLV2464CD has two independent shutdown pins: Pin 6 (1/2SHDN) disables Amplifiers A and B, and Pin 14 (3/4SHDN) disables Amplifiers C and D. Driving either pin below 0.7 V places its associated pair into ultralow-current mode (0.3 µA per channel), while the output enters high-impedance state - verified in the "Electrical Characteristics" table under IDD(SHDN).
What is the maximum capacitive load TLV2464CD can drive stably?
TLV2464CD maintains ≥30° phase margin driving up to 160 pF with 10 kΩ load (per Figure 36 and "Operating Characteristics" table). For loads exceeding 160 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation - a design constraint explicitly documented in the datasheet's stability analysis.
Can TLV2464CD operate from a single 3.3 V supply?
Yes, TLV2464CD is fully specified for single-supply operation from 2.7 V to 6 V, including 3.3 V. At VDD = 3.3 V, it retains rail-to-rail input/output swing, 6.4 MHz GBW, 1.6 V/µs slew rate, and 500 µA/channel supply current - all confirmed in the "Recommended Operating Conditions" and "Electrical Characteristics" sections of SLOS220J.
